A transfer assist member comprising a plurality of layers, one of said layers being a check film layer comprised of a crosslinked mixture of aminoplast resins and polyester polyol resins on a polymer support layer and wherein said polyester polyols are comprised of condensation polymers derived from an alcohol and an acid, and said alcohol is one of ethylene glycol, diethylene glycol, triethylene glycol, butylene glycol, propylene glycol, dipropylene glycol, neopentyl glycol, 1,5-pentanediol, 1,8-octanediol, 1,2-propanediol, 1,3-butanediol, 1,2-pentanediol, 2 methyl-2,4-pentanediol, bisphenol A, Z, C, S, trimethylol propane, glycerin, pentaerythritol, and sugar alcohols, and said acid is one of adipic acid, succinic acid, oxalic acid, malonic acid, glutaric acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, undecanedioic acid, dodecanedioic acid, maleic acid, fumaric acid, glutaconic acid, traumatic acid, and muconic acid, phthalic acid, isophthalic acid, and terephthalic acid, and mixtures thereof, further including a wear resistant layer comprised of a polyethylene, and wherein said wear resistant polyethylene layer is comprised of a high molecular weight polyethylene as represented by the following formula/structure
- wherein n represents the number of repeating segments of from about 100,000 to about 300,000, and wherein there is present an adhesive layer situated between each adjacent pair of said plurality of layers.
A composite toner transfer assist blade comprising a plurality of bonded layers and a bonded check film layer comprised of a partially conductive crosslinked mixture of aminoplast resins and polyester polyols layer contained on a polymer layer substrate of a polyalkylene terephthalate, a polyester, or mixtures thereof, and wherein the top layer of said plurality of layers is a wear resistant layer, wherein said aminoplast resin is selected from the group consisting of a melamine formaldehyde resin, a urea formaldehyde resin, a benzoguanamine formaldehyde resin, and a glycoluril formaldehyde resin, and said polyester polyol is selected from the group consisting of polyethylene adipate diol, polyethylene adipate-co-butylene adipate diol, polybutylene adipate diol, poly(2,2′-oxydiethylene adipate) diol, polyhexene adipate diol, polyethylene succinate diol, polyethylene succinate-co-butylene succinate diol, polybutylene succinate diol, poly(2,2′-oxydiethylene succinate) diol, polyhexene succinate diol, polyethylene phthalate diol, polyethylene phthalate-co-butylene phthalate diol, polybutylene phthalate diol, poly(2,2′-oxydiethylene phthalate) diol, polyhexene phthalate diol, poly(diethylene glycol-co-trimethylol propane) adipate polyol, poly(diethylene glycol-co-trimethylol propane) succinate polyol, or poly(diethylene glycol-co-trimethylol propane) phthalate polyol, and mixtures thereof, further including conductive components, acid catalysts, silicas, plasticizers, fluoropolymer particles of tetrafluoroethylene polymers, trifluorochloroethylene polymers, hexafluoropropylene polymers, vinyl fluoride polymers, vinylidene fluoride polymers, difluorodichloroethylene polymers polysiloxane polymers, and mixtures thereof.
