Abstract

Abstract Disclosed is a recording sheet which comprises (a) a substrate; (b) a coating on the substrate which comprises (1) a binder selected from the group consisting of (A) polyesters; (B) polyvinyl acetals; (C) vinyl alcohol-vinyl acetal copolymers; (D) polycarbonates; and (E) mixtures thereof; and (2) an additive having a melting point of less than about 65° C. and a boiling point of more than about 150° C. and selected from the group consisting of (1) furan derivatives; (2) cyclic ketones; (3) lactones; (4) cyclic alcohols; (5) cyclic anhydrides; (6) acid esters; (7) phosphine oxides; and (8) mixtures thereof; (c) an optional filler; (d) an optional antistatic agent; and (e) an optional biocide. Also disclosed is a process for generating images which comprises (1) generating an electrostatic latent image on an imaging member in an imaging apparatus; (2) developing the latent image with a toner which comprises a colorant and a resin selected from the group consisting of (A) polyesters; (B) polyvinyl acetals; (C) vinyl alcohol-vinyl acetal copolymers; (D) polycarbonates; and (E) mixtures thereof; and (3) transferring the developed image to a recording sheet which comprises (a) a substrate; (b) a coating on the substrate which comprises (1) a binder selected from the group consisting of (A) polyesters; (B) polyvinyl acetals; (C) vinyl alcohol-vinyl acetal copolymers; (D) polycarbonates; and (E) mixtures thereof; and (2) an additive having a melting point of less than about 65° C. and a boiling point of more than about 150° C. and selected from the group consisting of (1) furan derivatives; (2) cyclic ketones; (3) lactones; (4) cyclic alcohols; (5) cyclic anhydrides; (6) acid esters; (7) esters; (8) phenones; (9) phosphine oxides; and (10) mixtures thereof; (c) an optional filler; (d) an optional antistatic agent; and (e) an optional biocide.
