LIGHT-SENSITIVE RESIN COMPOSITION FOR THE ORIGINAL FORM FOR LETTERPRESS AND THE ORIGINAL FORM FOR LETTERPRESS RECEIVED FROM IT Russian patent published in 2019 - IPC G03F7/37 

FIELD: electrical engineering.

SUBSTANCE: present invention relates to a photosensitive resin composition for an original form for letterpress, as well as an original form for letterpress obtained from it. Photosensitive resin composition for the original letterpress form contains water soluble or dispersible polyamide as the main components, photopolymerizable unsaturated compound and photopolymerization initiator, the content in polyamide of alicyclic structural units derived from diamine, and alicyclic structural units derived from dicarboxylic acid, is from 30 to 90 mol. %, while among alicyclic structural units of polyamide content of alicyclic structural units derived from dicarboxylic acid, is 20 mol. % or more, as well as the original form for letterpress printing using the specified composition.

EFFECT: technical result is the development of a photosensitive resin composition for the original form for letterpress, which allows for reproducibility of printing gradation of light areas and durability of printing and allows for low stickiness of the surface of the form, as well as the development of the original form for letterpress printing using the specified composition.
