Patent ID: 7943681

Claim:
A radiation curable, ink jettable fluid composition, comprising: (a) an oligo/resin component; and (b) a radiation curable reactive diluent, wherein the reactive diluent comprises 0.5 to 30 weight percent of a high Tg component based on the total weight of reactive diluent, 0.1 to 50 weight percent of an adhesion promoting component based on the total weight of reactive diluent, wherein the adhesion promoting component comprises at least one of a heterocyclic radiation curable monomer and a monomer having a pendant alkoxylated moiety, and one or more multifunctional monomers having a plurality of radiation curable moieties, wherein the reactive diluent (i) comprises 0.5 to 25 weight percent of multifunctional radiation curable materials based on the total weight of reactive diluent, (ii) is free of monomers having three radiation curable moieties, and (iii) is free of alkoxylated radiation curable monomers having main-chain alkoxylated functionality, wherein the composition has a viscosity of up to about 50 centipoise at 25° C. and has an elongation of at least 50% in a cured state.
