FIELD: printing industry.
SUBSTANCE: invention relates to polygraphic consumable materials and can be used for production of film offset printing plates. Material has a polyethylene terephthalate film as a base on which an adhesive substrate and hydrophilous receiving layer are applied. The adhesive substrate includes polyvinylpyrrolidone, vinyl acetate copolymer with vinyl chloride and trichloracetic acid with the following ratio of the components, wt %: polyvinylpyrrolidone with 12600±2700 - 2.50÷66.66 of molecular weight, vinyl acetate copolymer with vinyl chloride - 5.00÷75.00, trichloracetic acid - 16.67÷75.00. Hydrophilous receiving layer includes polyvinyl alcohol, filler - kaolin, or iron oxide pigment, or their mixture and glutaric dialdehyde with the following ratio of the components, wt %: polyvinyl alcohol - 16.26÷33.11, kaolin - or iron oxide pigment, or their mixture - 63.49÷83.06, glutaric dialdehyde - 0.33÷4,76.
EFFECT: adhesion enhancement of layers that leads to efficient increase of run length.
