Abstract

The invention discloses a photosensitive elastomer composition with excellent ink affinity. The photosensitive elastomer composition comprises (A) a thermoplastic elastomer; (B) a liquid polyolefin plasticizer; (C) liquid polybutadiene of which the tail end is grafted with a hydrophilic group; (D) a monomer containing at least one unsaturated double bond functional group; (E) a photoinitiator or aphotoinitiation system; (F) auxiliaries. According to the flexographic resin plate containing the photosensitive elastomer composition having excellent ink affinity, the polymer liquid polybutadienecontaining hydrophilic groups is introduced into a photosensitive elastomer, so that the flexographic resin plate has excellent ink affinity; and the flexographic printing ink on an ink transfer roller is more easily accepted when the embossment image-text part using the flexographic resin plate is printed, so that the purpose of improving the quality of printed products is achieved.

Description

technical field [0001] The invention belongs to the technical field of letterpress printing, and in particular relates to a photosensitive elastomer composition with excellent ink affinity and a flexible resin plate containing the photosensitive elastomer composition. Background technique [0002] In recent years, flexible resin plates have been widely used in the printing of cartons, flexible packaging, labels and other easily deformed or soft substrates. At present, the common flexible resin plate technology has matured. Large foreign companies such as DuPont, Asahi Kasei, MacDermid, and Flint, and domestic Lekai Huaguang Printing Technology Co., Ltd. produce plates. With the rapid development of my country's economy, the volume of international trade will continue to increase, and the demand for flexible resin plates used in printing and packaging will also increase. [0003] However, compared with foreign countries, there is still a big gap in the quality of domesticall...
