Abstract

The invention provides a fiber containing (A) a polymer compound containing a structural unit having, in a side chain, at least one kind of organic group selected from a hydroxy group, a hydroxymethyl group and an alkoxymethyl group having 1-5 carbon atoms, and (B) a photoacid generator.

First claim

The invention claimed is:

1. A fiber comprising
(A) a polymer compound comprising (A1) structural units represented by formulas (1) and (2):

wherein
R 1 is a hydrogen atom or a methyl group,
Q 1 is an ester bond or an amide bond,
R 2 is an alkyl group having 1-10 carbon atoms or an aromatic hydrocarbon group having 6-10 carbon atoms, wherein at least one hydrogen atom is substituted by a hydroxy group, a hydroxymethyl group or an alkoxymethyl group having 1-5 carbon atoms,
R 3 is a hydrogen atom or a methyl group, and
R 4 and R 5 are the same or different and each is a hydrogen atom or an alkyl group having 1-4 carbon atoms optionally substituted by a hydroxy group or a carboxy group, and
(B) a photoacid generator.

2. The fiber according to claim 1 , wherein the above-mentioned polymer compound (A1) has a weight average molecular weight of 1,000-1,000,000.

3. The fiber according to claim 1 , further comprising (C) a crosslinking agent.

4. The fiber according to claim 1 , which is a photosensitive fiber.

5. The fiber according to claim 1 , comprising a nano fiber and/or a micro fiber.

6. A fiber pattern formed using the fiber according to claim 1 and a lithography method.

7. A substrate having the fiber pattern according to claim 6 on a surface thereof.

8. A biocompatible material comprising the fiber patterns according to claim 6 .

9. A biocompatible material comprising the fiber according to claim 1 .

10. A fiber comprising
(A) a polymer compound that is (A2) a natural polymer per se or comprises (A2) a natural polymer, and
(B) a photoacid generator.

11. The fiber according to claim 10 , wherein the above-mentioned (A2) natural polymer comprises at least one kind selected from dextrin and a derivative thereof.

12. The fiber according to claim 10 , wherein the above-mentioned (A2) natural polymer comprises a biopolymer.

13. A fiber formed from a composition comprising
(A) a polymer compound comprising a structural unit having, in a side chain, at least one kind of organic group selected from a hydroxy group, a hydroxymethyl group, and an alkoxymethyl group having 1-5 carbon atoms,
(B) a photoacid generator, and
(C) a crosslinking agent.
