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.
Claims13
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.
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.
