FIELD: printing industry. ^ SUBSTANCE: invention relates to printing consumable form materials and may be used to produce offset printing forms. Material represents a base paper, onto which at one side a hydrophilic layer (receiving layer) is applied, which receives laser printer toner well, at the other side - a hydrophobic layer (counterlayer). Counterlayer includes a hydrophobic film-forming polymer, in particular copolymer of vinyl acetate and vinyl chloride or its modified derivatives, or butyral resin, or cellulose acetobutyrate, or copolymer of butyl methacrylate, methyl methacrylate and methacrylic acid and trichloracetic acid. ^ EFFECT: invention makes it possible to minimise shrinkage of linear dimensions of printing form, which takes place in process of toner heat fixing in process of printing at laser printer and to increase mechanical strength of paper form in moist condition. ^ 2 tbl, 10 ex |
