Abstract
Abstract A new monomer triacrylyldiethylenetriamine is prepared by the reaction of diethylenetriamine acryloyl chloride and sodium hydroxide, the reaction yielding the desired monomer, sodium chloride and water. The monomer, triacrylyldiethylenetriamine, is useful in the photopolymerization process as high-speed polymerizable monomer in conjunction with a colloidal carrier and a light-sensitive ferric salt. Modification of the reactants in the above process allow for the production of polyacrylyl and polymethacrylyl polyethylene polyamines containing 2 to 4 ethylene groups.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
12 words
The photopolymerizable composition of claim 1 wherein said per-compound is a peroxide.
Claim 2
Dependent Claim
12 words
The photopolymerizable composition of claim 1 wherein said colloidal carrier is polyvinylpyrrolidone.
Claim 3
Dependent Claim
37 words
A photopolymerizable coating composition of increased photopolymerization speed comprising a polyvinylpyrroldone carrier containing a radiation-sensitive ferric compound and a polymerizable monomer comprising N,Ntriacrylyldiethylenetriamine, the ratio of the ferric ion to monomer being from 1:10,000 to 1: 6.
Claim 4
Dependent Claim
15 words
A photopolymerizable element comprising an image receptive support coated with the composition of claim 4.
Claim 5
Dependent Claim
72 words
A process of producing a polymeric photographic image which comprises irradiating to light, a coating of a colloidal carrier containing, as the photopolymerizable monomer, N,N-triacrylyldiethylenetriamine, and a radiation-sensitive ferric salt designed to produce ferrous ions imagewise by such irradiation and treating the irradiated coating with a per-compound to provide for the conjoint presence imagewise in said coating of said monomer, ferrous ions, and per-compound, to thereby cause imagewise polymerization of said monomer.
Claim 6
Dependent Claim
11 words
The process of claim 6 wherein said colloidal carrier is polyvinylpyrrolidone.
Claim 7
Dependent Claim
11 words
The process of claim 6 wherein said per-compound is a peroxide.
Claim 8
Dependent Claim
14 words
The process of claim 8 wherein said peroxide is present as an aqueous solution.
