Presensitized lithographic printing plate and method for preparing

A process for image forming by heat transfer method is disclosed. The process comprises the steps of (1) transferring an ink image from an ink layer of an ink sheet, which comprises a support and an ink layer provided on the support, to a surface of an intermediate image receiving layer of an intermediate image receiving sheet, which comprises a support and an image receiving layer provided on the support, by imagewise heating the ink layer, and (2) re-transferring the ink image transferred on the intermediate image receiving layer to a secondary image receiving sheet, In the above process, the ink layer comprises a coloring material and a homopolymer or a copolymer comprising a repeating unit derived from a monomer represented by the following Formula 1 or a phthalic polyester formed by polymerization of phthalic acid and a polyol; ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms; R.sub.2, R.sub.3 and R.sub.4 are each a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or a --COOR.sub.5 group, R.sub.5 a hydrogen atom or an alkyl group having 1 to 12 carbon atoms.

Heat transfer recording process using an intermediate recording sheet

Disclosed is a heat mode thermal transfer recording material comprising a support having thereon at least a light-heat converting layer containing a water-soluble colorant and an ink layer. The heat mode thermal transfer recording material is capable of forming transferred images excellent in color reproduction.

Heat mode thermal transfer recording material

An image forming process of an image forming material comprising a support and provided thereon, a photosensitive layer and a covering layer in that order comprises imagewise exposing the material by laser beam scanning, and peeling the covering film from the exposed material to form an image on the support or on the covering film, wherein said photosensitive layer contains a colorant, an addition-polymerizable or cross-linkable compound and a salt of a cationic dye with a borate anion represented by the following Formula (1): Formula (1) ##STR1##
