Abstract
Photosensitive compositions prepared without use of a chromium compound. The compositions exhibit high resolution and satisfactory sensitivity, and do not cause environmental pollution. The photosensitive compositions contain a water-soluble azide compound which serves as a photocrosslinking agent and poly(N-vinylacetamide) that is photocrosslinkable in the presence of the water-soluble azide compound.
Claims7
A photosensitive composition comprising a water-soluble azide compound serving as a photocrosslinking agent and poly(N-vinylacetamide) that is photocrosslinkable in the presence of the water-soluble azide compound.
A pattern formation method comprising:
- forming a photosensitive composition layer on a substrate by applying to said substrate a photosensitive composition comprising a water-soluble azide compound serving as a photocrosslinking agent and poly(N-vinylacetamide) that is photocrosslinkable in the presence of the water-soluble azide compound;
- (b) performing a pattern exposure on the photosensitive composition layer;
- and
- (c) subsequently developing the resulting exposed layer with water or an aqueous developer.
A photosensitive composition for the formation of a black matrix, which composition is used for the formation of a black matrix of color cathode-ray tubes and which contains a water-soluble azide compound serving as a photocrosslinking agent and a water-soluble polymer which is photocrosslinkable in the presence of the water-soluble azide compound, wherein the photocrosslinkable water-soluble polymer predominantly contains poly(N-vinylacetamide) and further contains another water-soluble polymer having reciprocity-law failure characteristics more prominent than those of the corresponding poly(N-vinylacetamide).
A photosensitive composition for the formation of a phosphor pattern, wherein said composition contains a water-soluble azide compound serving as a photocrosslinking agent;
- a water-soluble polymer which is photocrosslinkable in the presence of the water-soluble azide compound;
- and a phosphor;
- and which is prepared by dissolving or dispersing these in an aqueous medium, wherein the photocrosslinkable water-soluble polymer contains poly(N-vinylacetamide).
A photosensitive composition for the formation of a color filter, wherein said composition contains a water-soluble azide compound serving as a photocrosslinking agent;
- a water-soluble polymer which is photocrosslinkable in the presence of the water-soluble azide compound, and a pigment;
- and which is prepared by dissolving or dispersing these in an aqueous medium, wherein the photocrosslinkable water-soluble polymer contains poly(N-vinylacetamide).
