Polymeric absorber for laser-colorant transfer

摘要

A colorant-donor element for thermal colorant transfer comprising a support having thereon a colorant layer having a laser radiation-absorbing material associated therewith, wherein the laser radiation-absorbing material comprises a polymer containing within its repeat units a laser radiation-absorbing chromophore comprising an organic moiety having a plurality of conjugated double bonds and an optical absorption of from about 400 to about 1200 nm, and wherein the organic moiety is capable of forming at least two covalent bonds to the polymer backbone.
