Abstract
Abstract Radiation-curable vehicles, and compositions containing such vehicles, for use in inks, paints, coatings, or similar compositions, such vehicles being operative without the inclusion of photo-initiators or photo-decomposible materials to accelerate the cure, and comprising condensation products of aldehydes and ketones, and such compositions being substantially free of acrylic or allylic moieties.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
87 words
A radiation-curable film-forming vehicle consisting essentially of a radiation-curable film-forming agent consisting of a mixture of (a) a substantially saturated ketone resin having a molecular weight of from about 500 to about 1200 and formed by the condensation of an aldehyde and a cyclic or acyclic ketone and (b) an extender, said ketone resin being present in the mixture in an effective amount to form a radiation-curable film, and said extender being selected from the group consisting of esters, alcohols, aldehydes, nitrogen heterocyclics, epoxides, nitriles, and carbamates.
Claim 2
Dependent Claim
87 words
A radiation-curable film-forming vehicle consisting essentially of a radiation-curable film-forming agent consisting of a mixture of (a) a substantially saturated ketone resin having a molecular weight of from about 500 to about 1200 and formed by the condensation of an aldehyde and a cyclic or acyclic ketone and (b) an extender, said ketone resin being present in the mixture in an effective amount to form a radiation-curable film, and said extender being selected from the group consisting of esters, alcohols, aldehydes, nitrogen heterocyclics, epoxides, nitriles, and carbamates.
Claim 3
Dependent Claim
22 words
The vehicle of claim 1 wherein the ratio of ketone resin to extender is between about 1:3 and 3:1 parts by weight.
Claim 4
Dependent Claim
29 words
The vehicle of claim 1 wherein the ratio of ketone resin to extender is about 55 parts by weight of resin to about 45 parts by weight of extender.
Claim 5
Dependent Claim
16 words
The vehicle of claim 1 further consisting of an effective amount of at least one photo-initiator.
Claim 6
Dependent Claim
19 words
The vehicle of claim 4 wherein the photo-initiator is selected from the group consisting of benzophenone and Michler's Ketone.
Claim 7
Dependent Claim
28 words
A radiation-curable composition comprising the vehicle of claim 1 and at least one coloring agent, said coloring agent being present in an effective amount to color the vehicle.
Claim 8
Dependent Claim
28 words
The composition of claim 6 wherein there is included an effective amount to permit smooth application of the composition to a substrate of at least one slip agent.
Claim 9
Dependent Claim
26 words
The composition of claim 7 wherein said slip agent is selected from the group consisting of micronized polyethylene, micronized polytetrafluoroethylene, talc, silica aerogel, and silicone oil.
Claim 10
Dependent Claim
17 words
The composition of claim 6 wherein there is included an effective amount of at least one photo-initiator.
Claim 11
Dependent Claim
19 words
The composition of claim 7 wherein said photo-initiator is selected from the group consisting of benzophenone and Michler's Ketone.
Claim 12
Independent Claim
130 words
A method of imprinting a substrate which comprises (a) applying to said substrate a composition consisting essentially of a substantially saturated ketone resin having a molecular weight of from about 500 to 1200 and formed by the condensation of an aldehyde and a cyclic or acyclic ketone, an extender selected from the group consisting of esters, alcohols, aldehydes, nitrogen heterocyclics, epoxides and nitrites, and a coloring agent, said ketone resin being present in an effective amount to form a cured film when subjected to radiation, said extender being present in an effective amount to homogeneously disperse or solublize said ketone resin, and said coloring agent being present in an effective amount to color the radiation-cured ketone resin, and (b) applying an effective amount of radiation to cure said ketone resin.
Claim 13
Independent Claim
130 words
A method of imprinting a substrate which comprises (a) applying to said substrate a composition consisting essentially of a substantially saturated ketone resin having a molecular weight of from about 500 to 1200 and formed by the condensation of an aldehyde and a cyclic or acyclic ketone, an extender selected from the group consisting of esters, alcohols, aldehydes, nitrogen heterocyclics, epoxides and nitrites, and a coloring agent, said ketone resin being present in an effective amount to form a cured film when subjected to radiation, said extender being present in an effective amount to homogeneously disperse or solublize said ketone resin, and said coloring agent being present in an effective amount to color the radiation-cured ketone resin, and (b) applying an effective amount of radiation to cure said ketone resin.
Claim 14
Dependent Claim
30 words
The method of claim 11 wherein said composition further consists of an effective amount of at least one slip agent to permit smooth application of the composition to the substrate.
Claim 15
Dependent Claim
17 words
The method of claim 11 wherein said composition further consists of an effective amount of a photo-initiator.
