Claims
- 1. A light-sensitive coating liquid with improved storability comprising:
- a light-sensitive composition selected from the group consisting of a positive light-sensitive composition containing an o-quinonediazide compound and a negative light-sensitive substance containing a diazo resin;
- a dye;
- 3-methoxy-1-butanol as an organic solvent; and
- at least one solvent selected from the group consisting of diethylene glycol monomethyl ether and diethylene glycol dimethyl ether.
- 2. The light-sensitive coating liquid according to claim 1, wherein said another solvent is diethylene glycol dimethyl ether present at a ratio of 30% by weight to 60% by weight based on the total amount of the solvents.
- 3. The light-sensitive coating liquid according to claim 1, further comprising a fluorine type surfactant.
- 4. The light-sensitive coating liquid according to claim 3, wherein the fluorine type surfactant is a methacrylate or acrylate polymer having fluorinated alkyl group in the side chain.
- 5. The light-sensitive coating liquid according to claim 4, wherein the methacrylate or acrylate polymer has a number average molecular weight calculated on the standard polystyrene in the range of 30,000 or less.
- 6. The light-sensitive coating liquid according to claim 4, wherein the acrylate structural unit or the methacrylate structural unit at the moiety having the fluorinated alkyl group in the side chain of the methacrylate or acrylate polymer is a compound represented by the the formula (IV) or the formula (V) shown below: Formula (IV) ##STR19## wherein R is hydrogen atom or methyl group, n represents an integer of 0 to 20, a 0 to 2 and b 0 to 1, Formula (V) ##STR20## wherein R is hydrogen atom or methyl group, n represents an integer of 0 to 10, m 0 to 20 and a 0 to 2.
- 7. The light-sensitive coating liquid according to claim 4, wherein the (meth)acrylate polymers having the fluorinated alkyl group in the side chain has further an alkylene oxide group or an alkyl group in the side chain, and has the structural formula represented by the formula (VI) or (VII) shown below: Formula (VI): ##STR21## wherein R represents hydrogen atom or methyl group, n represents an integer of 1 to 6 and m 1 to 10, Formula (VII): ##STR22## wherein R represents hydrogen atom or methyl group and n represents an integer of 1 to 22.
- 8. The light-sensitive coating liquid according to claim 3, wherein the fluorine type surfactant is contained in an amount of 0.02 to 0.2% by weight based on the solids contained in the light-sensitive coating liquid.
- 9. The light-sensitive coating liquid according to claim 3, wherein the fluorine type surfactant is contained in an amount of 0.025 to 0.1% by weight based on the solids contained in the light-sensitive coating liquid.
