Abstract

A process including providing a substantially flat printed image on a substrate; disposing a curable gellant composition onto the printed image in registration with the printed image, successively depositing additional amounts of the gellant composition to create a raised image in registration with the printed image; and curing the deposited raised image. A process including providing a printed image on a substrate; disposing a curable non-gellant composition onto the printed image in registration with the printed image; and disposing a curable gellant composition onto the printed image in registration with the printed image; to create a raised image in registration with the printed image; and curing the deposited raised image. An ultraviolet curable phase change gellant composition including a radiation curable monomer or prepolymer, a photoinitiator, a silicone polymer or pre-polymer, and a gellant.

First claim

The invention claimed is:

1. A process comprising:
providing a substantially flat printed image on a substrate;
disposing a curable gellant composition onto the printed image in registration with the printed image, wherein the curable gellant composition comprises a radiation curable monomer or prepolymer, a photoinitiator, and a gellant;
successively depositing additional amounts of the gellant composition to create a raised image in registration with the printed image; and
curing the deposited raised image,
wherein the curable gellant composition further comprises a silicone polymer or pre-polymer.

2. The process of claim 1 , wherein the printed image is a xerographic image.

3. The process of claim 1 , wherein the process comprises an in-line process.

4. The process of claim 1 , wherein the cured raised image has a height of greater than 30 micrometers.

5. The process of claim 1 , wherein the raised image has a height of from about 40 micrometers to about 60 micrometers.

6. The process of claim 1 , wherein curing the deposited curable gellant composition comprises curing after the last of the successive additional amounts of the curable gellant composition are deposited.

7. The process of claim 1 , wherein the curable gellant is free of colorant.

8. The process of claim 1 , wherein the at least one curable monomer or prepolymer is a multifunctional acrylate or methacrylate compound.

9. The process of claim 1 , wherein the photoinitiator is selected from the group consisting of benzyl ketones, monomeric hydroxyl ketones, α-alkoxy benzyl ketones, α-amino ketones, acyl phosphine oxides, metallocenes, benzophenone, benzophenone derivatives, isopropyl thioxanthenones, arylsulphonium salts and aryl iodonium salts.

10. The process of claim 1 , wherein the substrate comprises a member of the group consisting of plain paper, ruled notebook paper, bond paper, silica coated paper, glossy coated paper, transparency materials, fabrics, textile products, plastics, polymeric films, metal, wood, wax, and salts.

11. A process comprising:
providing a substantially flat printed image on a substrate;
disposing a curable gellant composition onto the printed image in registration with the printed image; and
disposing a curable non-gellant composition onto the printed image in registration with the printed image to create a raised image in registration with the printed image; and
curing the deposited raised image,
wherein the curable gellant composition further comprises a silicone polymer or pre-polymer.

12. The process of claim 11 , wherein the printed image is a xerographic image.

13. The process of claim 11 , wherein the raised image has a height of from about 40 micrometers to about 60 micrometers.

14. The process of claim 11 , wherein curing the deposited raised image comprises curing after the last of successive additional amounts of the curable non-gellant composition and curable gellant composition are deposited.

15. The process of claim 11 , wherein the raised image created is a Braille image.

16. The process of claim 11 , wherein the curable gellant composition and the curable non-gellant composition are disposed sequentially onto the substantially flat printed image;
wherein the curable gellant composition is disposed first and the curable non-gellant composition is disposed second.

17. The process of claim 11 , wherein the curable non-gellant composition comprises a radiation curable monomer or prepolymer, and a photoinitiator; and
wherein the curable gellant composition comprises a radiation curable monomer or prepolymer, a photoinitiator, and a gellant.
