Abstract: An improved process for the diazo-type multicolor reproduction which can give multicolored copies excellent in the hue separation and can increase the number of copies obtained from an original treated with a color-forming agent is disclosed. This improved multicolor reproduction process is characterized by the use of a color-forming composition comprising a thermo-volatile or sublimable coupler and at least one hue separation-improving agent selected from polyalkylene oxides and polyalkylene oxide derivatives which are solid under normal conditions and fatty acid derivatives having a melting point of at least 100 DEG C.

Abstract: A transfer sheet for electrostatically transferring thereon an electrically conductive or electrically semi-conductive toner in electrostatic photography or electrostatic printing, which comprises a paper substrate and a toner-receiving layer formed on at least one surface of the substrate, said tonerreceiving layer consisting essentially of a composition comprising (A) 100 parts by weight a thermoplastic acrylicstyrene copolymer having an acid value from 10 to 170 and (B) 10 to 100 parts by weight of finely divided fumed silica is disclosed. In this transfer sheet, the electric resistance can be maintained at a high level even under high humidity conditions, and a toner image can be transferred on this transfer sheet at a high transfer efficiency without broadening of contours of the image. This transfer sheet has feel and touch quite similar to those of ordinary paper and is very excellent in graphic characteristics.
