Abstract

A laminated polyester film provided on at least one side with layer (X) made from acrylic urethane copolymer resin (A), isocyanate compound (B), epoxy compound (C), compound (d-1) having a polythiophene structure and compound (d-2) having an anion structure, wherein the layer (X) has a continuous phase structure.

First claim

The invention claimed is:

1. A forming member made from a laminated polyester film provided on at least one side with layer (X) made from an acrylic urethane copolymer resin (A), an isocyanate compound (B), an epoxy compound (C), a compound (d-1) having a polythiophene structure and a compound (d-2) having an anion structure, wherein the layer (X) has a continuous phase structure, the laminated polyester film is provided with a scratch-resistant resin layer on at least one side, and the scratch-resistant resin layer is one of outermost layers while the polyester film, the layer (X) and the scratch-resistant resin layer are disposed in series on the one side, and the scratch-resistant resin layer contains a polycaprolactone constituent (K) and a urethane constituent (N) together with a polysiloxane constituent (L) and/or a polydimethyl siloxane constituent (M).

2. The forming member according to claim 1 , wherein the layer (X) has the continuous phase structure between a first mixture and a second mixture, the first mixture comprising the acrylic urethane copolymer resin (A) and the isocyanate compound (B), the second mixture comprising the epoxy compound (C), the compound (d-1) having the polythiophene structure and the compound (d-2) having the anion structure.

3. The forming member according to claim 1 , wherein the laminated polyester film further comprises a scratch-resistant resin layer on at least one side, and the scratch-resistant resin layer is one of outermost layers while the polyester film, the layer (X) and the scratch-resistant resin layer are disposed in series on the one side, a thickness of the scratch-resistant resin layer is 10 to 30 μm, and a surface specific resistance of the scratch-resistant resin layer is less than 1×10 13 Ω/□.

4. The forming member according to claim 3 , wherein the scratch-resistant resin layer is formed by coating on a side of the layer (X) of the laminated polyester film with a scratch-resistant resin layer-constituting liquid that contains a heat-curable resin to be heated or an active ray-curable resin to be irradiated with an active ray.

5. A formed body made by coating the laminated polyester film of the forming member according to claim 1 with a thermoplastic resin.

6. The forming member according to claim 1 , the scratch-resistant resin layer formed by coating on a side of the layer (X) of the laminated polyester film with a scratch-resistant resin layer-constituting liquid that contains resin (k) having a polycaprolactone skeleton and a hydroxyl group and an isocyanate-based compound (n), and at least one of resins selected from the group consisting of resin (l) having a polysiloxane skeleton, resin (m) having a polydimethyl siloxane skeleton and resin (l+m) having a polysiloxane skeleton and a polydimethyl siloxane skeleton.

7. A laminated polyester film provided on at least one side with layer (X) made from an acrylic urethane copolymer resin (A), an isocyanate compound (B), an epoxy compound (C), a compound (d-1) having a polythiophene structure and a compound (d-2) having an anion structure, wherein the layer (X) contains 100 parts by weight of the resin (A), 80 to 110 parts by weight of the compound (B), 60 to 90 parts by weight of the compound (C), and 10 to 30 parts by weight of a total of the compound (d-1) and the compound (d-2).

8. The laminated polyester film according to claim 7 , wherein the layer (X) has a continuous phase structure.

9. The laminated polyester film according to claim 8 , wherein the layer (X) has the continuous phase structure between a first mixture and a second mixture, the first mixture comprising the acrylic urethane copolymer resin (A) and the isocyanate compound (B), the second mixture comprising the epoxy compound (C), the compound (d-1) having the polythiophene structure and the compound (d-2) having the anion structure.

10. The laminated polyester film according to claim 7 , wherein the layer (X) contains 100 parts by weight of the resin (A), 50 to 80 parts by weight of oxazoline compound (E) and 50 to 80 parts by weight of carbodiimide compound (F).

11. A method of manufacturing a laminated polyester film comprising coating on at least one side of a polyester film, before crystalline orientation, with a coating agent (x) to form layer (X), stretching the polyester film in at least one direction, and heating the polyester film, wherein the coating agent contains an acrylic urethane copolymer resin (a), an isocyanate compound (b), an epoxy compound (c), a compound (d-1) having a polythiophene structure and a compound (d-2) having an anion structure, and the coating agent (x) contains 100 parts by weight of resin (a), 80 to 110 parts by weight of compound (b), 60 to 90 parts by weight of compound (c), and 10 to 30 parts by weight of a total of compound (d-1) and compound (d-2).

12. The method according to claim 11 , wherein the layer (X) has a continuous phase structure between a first mixture and a second mixture, the first mixture comprising the acrylic urethane copolymer resin (A) and the isocyanate compound (B), the second mixture comprising the epoxy compound (C), the compound (d-1) having the polythiophene structure and the compound (d-2) having the anion structure, the acrylic urethane copolymer resin (A) comprising the acrylic urethane copolymer resin (a) or a resin having a structure derived from the acrylic urethane copolymer resin (a), the isocyanate compound (B) comprising the isocyanate compound (b) or a resin having a structure derived from the isocyanate compound (b), the epoxy compound (C) comprising the epoxy compound (c) or a resin having a structure derived from the epoxy compound (c).

13. The method according to claim 11 , wherein the coating agent (x) contains 100 parts by weight of the resin (a), 50 to 80 parts by weight of an oxazoline compound (e) and 50 to 80 parts by weight of a carbodiimide compound.
