Abstract
Abstract Radiation curable compositions particularly suitable for use by electron beam are disclosed, comprising a monomer of the formula: <IMAGE> in which R1 is H or alkyl of 1 to 4 carbon atoms; R2 is alkylene or alkylene ether; and R3 is alkylcycloalkyl, phenyl or substituted phenyl; and a polyfunctional acrylate of an alkylacrylate curing agent, e.g., the adduct of acrylic acid and a diglycidyl ether of Bisphenol A.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
A radiation curable composition comprising 20 to 80 weight percent of a monomer of the formula: ##STR12## in which R 1 is H or alkyl of 1 to 4 carbons; R 2 is an alkylene or alkylene ether radical of 2 to 6 carbon atoms; R 3 is alkyl of 1 to 12 carbon atoms; cycloalkyl or substituted cycloalkyl of 5 to 12 carbon atoms; phenyl or substituted phenyl; and 20 to 80 weight percent of a polyfunctional acrylate or polyfunctional alkyl-substituted acrylate crosslinking agent.
Claim 2
Dependent Claim
85 words
A radiation curable composition comprising 20 to 80 weight percent of a monomer of the formula: ##STR12## in which R 1 is H or alkyl of 1 to 4 carbons; R 2 is an alkylene or alkylene ether radical of 2 to 6 carbon atoms; R 3 is alkyl of 1 to 12 carbon atoms; cycloalkyl or substituted cycloalkyl of 5 to 12 carbon atoms; phenyl or substituted phenyl; and 20 to 80 weight percent of a polyfunctional acrylate or polyfunctional alkyl-substituted acrylate crosslinking agent.
Claim 3
Dependent Claim
11 words
The composition of claim 1 in which R 1 is H.
Claim 4
Dependent Claim
13 words
The composition of claim 1 in which R 1 is -CH 3 .
Claim 5
Dependent Claim
13 words
The composition of claim 1 in which R 2 is an ethylene radical.
Claim 6
Dependent Claim
17 words
