Abstract D R A W I N G The irradiation can be carried out imagewise so as to reproduce images, e.g. illustrations, printed wording etc. on the substrate, said image being developed by washing out the unexposed unbonded polymeric dyestuff. WHEREIN A is the residue of an aliphatic alcohol containing m hydroxyl groups and a molecular weight less than 300, m is 1 to 6, R is lower-alkyl or halogen, x is 1 to 2, y is 0 to 2, provided that x + y is 3, and further provided that m is at least 2 when x is 1, the SO2N3 groups are in positions 3, 4, or 5 of the benzene nuclei and one of said positions is unsubstituted and R'' Polymeric dyestuffs are bonded to substrates containing a plurality of C-H bonds (polyolefins such as polyethylene preferred) by applying the polymeric dyestuffs in association with certain sulfonazides as a coating to the substrate and exposing the coated substrate to irradiation (thermal or actinic). The sulfonazides used have the formulas:
The process of claim 1 wherein said sulfonazide is ethylenebis(p-azidosulfonylcarbanilate).
Claim 2
Dependent Claim
11 words
The process of claim 1 wherein said sulfonazide is glycerol tris(p-azidosulfonylcarbanilate).
Claim 3
Dependent Claim
11 words
The process of claim 1 wherein said sulfonazide is N,N'' ,N-''''-tris(p-azidosulfonylphenyl)isocyanurate.
Claim 4
Dependent Claim
29 words
The process of claim 1 wherein the polymeric dyestuff is a poly(maleic anhydride-co-methylvinyl ether) which has been modified by reaction with a basic dyestuff containing a free amino group.
Claim 5
Dependent Claim
16 words
The process of claim 1 wherein the substrate containing a plurality of C-H bonds is polyethylene.
Claim 6
Dependent Claim
55 words
A process of chemically bonding a polymeric dyestuff to a polyolefin which process comprises the steps of: a. applying to said polyolefin a coating comprising a polymeric dyestuff and from 1 percent to 15 percent by weight, based on said polymeric dyestuff, of a sulfonazide selected from the class consisting of sulfonazides having the formulas:
Claim 7
Dependent Claim
16 words
The process of claim 7 wherein the irradiation of the coated polyolefin is carried out imagewise.
Claim 8
Dependent Claim
10 words
The process of claim 7 wherein said sulfonazide is ethylene-bis(p-azidosulfonylcarbanilate).
Claim 9
Dependent Claim
11 words
The process of claim 7 wherein said sulfonazide is glycerol tris(p-azidosulfonylcarbanilate).
Claim 10
Dependent Claim
13 words
The process of claim 7 wherein said sulfonazide is N,N'' , N''''-tris(p-azidosulfonylphenyl)isocynaurate. -tris(p-azidosulfonylphenyl)isocyanurate.
