Abstract

A method for modifying the degree of gloss of a surface. The method including the steps of a) providing an object; b) applying to at least one surface of the object, a powder composition comprising a thermosetting binder; c) applying onto the at least one surface of the resulting object in b), a fluid composition; and d) applying heat and pressure to the resulting surface from c) with a press plate in a pressing device.

First claim

The invention claimed is:

1. A method for modifying the degree of gloss of a surface, the method comprising the steps of:
a) providing an object;
b) applying a powder composition comprising a thermosetting binder to at least one surface of the object;
c) applying onto the powder composition on the at least one surface of the object a fluid composition;
d) applying heat and pressure to the resulting surface from c) with a press plate in a pressing device at a pressing temperature,
wherein the fluid composition is uncolored and has a boiling temperature that is higher than the pressing temperature.

2. The method according to claim 1 , wherein the pressing device is a continuous pressing device or a static pressing device.

3. The method according to claim 1 , wherein the pressing step takes place under a temperature of about 120° C. to about 250° C.

4. The method according to claim 1 , wherein the pressing step employs a pressure of about 10 bar to about 90 bar.

5. The method according to claim 1 , wherein the pressing step has a duration of about 1 second to about 120 second.

6. The method according to claim 1 , wherein the fluid composition is a monoethylene based fluid or a water based ink composition.

7. The method according to claim 1 , wherein the thermosetting binder of the powder composition is an amino resin.

8. The method according to claim 1 , wherein the thermosetting binder of the powder composition is a melamine formaldehyde resin, a urea formaldehyde resin, or a phenol formaldehyde resin.

9. The method according to claim 1 , wherein the powder composition comprises one or more of various fibre components, resins, pigments, binders, and fillers such as barium sulphate, various types of kaolin clay, talcum or chalk.

10. The method according to claim 1 , wherein the fluid composition is applied by printing, digital printing, spraying or spraying through a template.

11. The method according to claim 1 , wherein the powder composition comprises one or more of cellulose fibres, a melamine-formaldehyde resin, colour pigments, and/or metal oxides such as, e.g., Al 2 O 3 .

12. The method according to claim 1 , wherein the powder composition is applied onto the at least one surface of the object by scattering, printing or spraying.

13. A method for modifying the degree of gloss of a surface, the method comprising the steps of:
i) providing a sheet or a carrier impregnated with a thermosetting binder;
ii) applying a fluid composition onto the sheet or carrier;
iii) applying the resulting sheet in ii) onto a surface of an object;
iv) optionally heating the resulting surface of the object in step iii);
v) applying heat and pressure to the resulting surface of the object in iii) or iv) with a pressing device at a pressing temperature,
wherein the fluid composition is uncolored and has a boiling temperature that is higher than the pressing temperature.

14. The method according to claim 13 , wherein the sheet is a paper or cellulose based sheet, a sheet based on a polymeric material or any combinations thereof.

15. The method according to claim 13 , wherein the pressing device is a continuous pressing device or a static pressing device.

16. The method according to claim 13 , wherein the pressing step takes place under a temperature of about 120° C. to about 250° C.

17. The method according to claim 13 , wherein the pressing step employs a pressure of about 10 bar to about 90 bar.

18. The method according to claim 13 , wherein the pressing step has a duration of about 1 second to about 120 second.

19. The method according to claim 13 , wherein the fluid composition is a monoethylene based fluid or a water based ink composition.

20. The method according to claim 13 , wherein the fluid composition is applied by printing, digital printing, spraying, or spraying thorough a template.

21. The method according to claim 13 , wherein the optional heating step is performed by employing IR radiation or blowing with a heated air stream.

22. The method according to claim 13 , wherein the method comprises creating a matt or lusterless surface on an area of the surface to which the fluid composition has been applied, wherein areas on which no fluid composition has been applied appear glossy.

23. The method according to claim 13 , wherein the surface of the pressing device is completely unstructured or contains various degrees of structure.

24. An object obtainable by the method according to claim 13 .

25. The object according to claim 24 , wherein the object comprises an essentially plane surface.

26. An object comprising at least one surface which further comprises a pressed powder wherein a fluid composition is encapsulated and wherein the area comprising the encapsulated fluid gives a matt or lusterless appearance to the surface, wherein the matt or lusterless appearance has a gloss level of less than 10 GU, measured using the 85° angle on a glossmeter, wherein the fluid composition is uncolored and has a boiling temperature that is higher than a pressing temperature.

27. The object according to claim 26 , wherein the object comprises an essentially plane surface.

28. The method according to claim 1 , wherein a fluid composition is encapsulated in the pressed surface, and wherein an area comprising the encapsulated fluid gives a matt or lusterless appearance to the pressed surface, wherein the pressed surface, wherein the matt or lusterless appearance has a gloss level of less than 10 GU, measured using the 85° angle on a glossmeter.

29. The method according to claim 13 , wherein a fluid composition is encapsulated in the pressed surface, and wherein an area comprising the encapsulated fluid gives a matt or lusterless appearance to the pressed surface, wherein the pressed surface, wherein the matt or lusterless appearance has a gloss level of less than 10 GU, measured using the 85° angle on a glossmeter.

30. The method according to claim 1 , wherein the fluid composition is a monoethylene based fluid.

31. The method according to claim 13 , wherein the fluid composition is a monoethylene based fluid.

32. The method according to claim 13 , wherein the fluid composition is transparent.
