<p>A dye-donor element for thermal dye transfer has a support carrying a dye layer on one side and on the other side, in order, a subbing layer and a slipping layer. The subbing layer antistatic properties and contains (1) a polymer which has a molecular wt. of at least 100,000 and contains at least 25 wt. % of a repeating unit contg. an alkylene oxide segment, and (2) a copolymer of Formula (I). The copolymer (I) is present in the layer in the amt. 30-75 wt. %. A = an addition polymerisable monomer contg. at least two ethylenically unsatd. gps.; B = a copolymerisable alpha ,beta -ethylenically unsatd. monomer; L = a carboxylic gp. or ad aromatic ring; Q = N or P; R1, R2 and R3 = 1-20 C alkyl, 6-10 C aryl or 6-10 C aralkyl; R4 - H or CH3; M = an anion; n = 1-6; x = 0-20 mol. %; y = 0-90 mol. %; and z = 10-100 mol. %. Also claimed is (A) a thermal dye transfer assembly comprising the above dye donor element and a dye receiving element, and (B) a method of forming a dye transfer image involving heating the above dye donor element imagewise and transferring the image to a receiving element. The polymer (2) is pref. polyethylene oxide, poly butyl acrylate/propylene glycol monomethacrylate/methyl 2-acrylamido-2- methoxyacetate, polypropylene glycol, or poly n-butyl acrylate/polypropylene glycol monomethacrylate/methyl 2-acrylamido-2- methoxyacetate. The polymer (2) is poly N-vinyl benzyl- N,N,N-trimethylammonium chloride/ethylene glycol dimethacrylate (93/7 mol. %), poly 2-(N,N,N-trimethylammonium) ethyl (meth)acrylate methosulphate, or poly 2-(N,N-diethylamino)ethyl methacrylate hydrogen chloride/ethylene glycol dimethacrylate (93/7 mole %). Most. pref. the subbing layer contains polyethylene oxide and poly N-vinylbenzyl- N,N,N-trimethylammonium chloride/ethylene glycol dimethacrylate (93/7 mole %).</p> |
