Abstract
Abstract A non-silver light-sensitive composition according to the invention consists of the following components, in percent by weight; ______________________________________ a hydroxyderivative of naphthalene 1 to 10 an aromatic amine 29 to 60 saturated halogenated hydrocarbon 35 to 29 a polymeric binder 35 to 1. ______________________________________ The composition of the present invention makes it possible to produce light-sensitive layers which have an increased sensitivity (2×10 -4 J/cm 2 at 365 nm) and a low optical fog density (D. below 0.05).

22 words
A non-silver light-sensitive composition according to claim 2, wherein as the polymeric binder use is made of polystyrene, polymethylmethacrylate, polyvinylacetate, polyvinylchloride, polycarbonate.
Claim 5
Dependent Claim
119 words
Method of producing images, which comprises exposing to light on a substrate a non-silver light-sensitive composition consisting of, in percent by weight: ______________________________________
a hydroxyderivative of naphthalene selected from
the group consisting of α-naphthol, β-naphthol,
1-naphtholphthalein; aminonaphthol and
dihydroxynaphthalene as anti fogging agent
1 to 10

consisting of diphenylbenzlamine, indole and
dibenzylaniline as color former
29 to 60
a saturated halogenated hydrocarbon as
photoactivator 35 to 29
a polymeric binder 35 to 1.
______________________________________ until a latent image is formed, intensifying the thus formed image by exposing the same to visible light with an intensity of 0.1 to 1.0 W/cm 2 for 1-5 minutes, and fixing the resulting image by heat treatment.
Claim 6
Dependent Claim
119 words
Method of producing images, which comprises exposing to light on a substrate a non-silver light-sensitive composition consisting of, in percent by weight: ______________________________________
a hydroxyderivative of naphthalene selected from
the group consisting of α-naphthol, β-naphthol,
1-naphtholphthalein; aminonaphthol and
dihydroxynaphthalene as anti fogging agent
1 to 10
an aromatic amine selected from the group
consisting of diphenylbenzlamine, indole and
dibenzylaniline as color former
29 to 60
a saturated halogenated hydrocarbon as
photoactivator 35 to 29
a polymeric binder 35 to 1.
______________________________________ until a latent image is formed, intensifying the thus formed image by exposing the same to visible light with an intensity of 0.1 to 1.0 W/cm 2 for 1-5 minutes, and fixing the resulting image by heat treatment.
Claim 7
Dependent Claim
17 words
Method according to claim 4 wherein the heat treatment is effected at 100°-140° C. for 1-30 minutes.
Claim 8
Dependent Claim
22 words
Method according to claim 4 wherein the treatment is effected at a temperature of 220°-260° C. for a period of 2-3 minutes.
Claim 9
Dependent Claim
26 words
Method according to claim 6 wherein said polymeric binder is polyvinylchloride and wherein after the heat treatment the resulting image is treated with dichloroethane or acetone.
Claim 10
Dependent Claim
67 words
Method according to claim 4, wherein the composition of claim 6 is exposed through a color-dividing negative and wherein the composition includes an indol producing red colored image as the aromatic amine, repeating the exposing, intensification and heat treatment two times with light sensitive compositions including diphenylbenzylamine as the aromatic amine producing blue-colored image and dibenzylaniline to produce a yellow colored image, thereby obtaining a multi-colored image.
