Embodiment 1

[0027] The invention comprises a support (5), a photosensitive elastomer (3) and a protective film (1), an adhesive layer (4) is arranged between the support (5) and the photosensitive elastomer (3), and the photosensitive elastomer (3) A layer of anti-adhesive layer (2) is compounded on the top, and the anti-adhesive layer (2) contains dye, and the maximum absorption wavelength of the dye is 450nm. As a preferred solution, the dye is a red dye or a mixture of red dyes. The weight ratio of the dye to the total solids of the release layer material is 0.01%.

[0028] The preparation method of the flexible photosensitive resin plate is to compound one or more anti-adhesive layers containing 0.01% dye on the photosensitive elastomer that has been kneaded at a temperature of 20 ° C and a pressure of 0.15 MPa, and then remove the protective film. Expose, make a plate, and get a flexible photosensitive resin plate. The dye is preferably a red dye or a mixture of red dyes. Or, as a...

Embodiment 2

[0030] The invention comprises a support (5), a photosensitive elastomer (3) and a protective film (1), an adhesive layer (4) is arranged between the support (5) and the photosensitive elastomer (3), and the photosensitive elastomer (3) Two anti-adhesive layers (2) are compounded on it, and at least one anti-adhesive layer (2) contains a dye, and the maximum absorption wavelength of the dye is 750nm. The dye is a red dye or a mixture of red dyes. The dye should use Neozapon  Red 335 or Red Base 543 or Zapon Red 335 / 395 or Neozapon  Red 395 or Neozapon  One of Red 346 or Valifast Red 3306 or Valifast Red 3320 or their mixture. The amount of the dyestuff is 3% by weight of the total solids of the release layer material.

[0031] The preparation method of the flexible photosensitive resin plate in the present invention: on the photosensitive elastomer that has been kneaded, at a temperature of 130 ° C and a pressure of 14 MPa, one or more anti-adhesive layers containing 3%...

Embodiment 3

[0033] The invention comprises a support (5), a photosensitive elastomer (3) and a protective film (1), an adhesive layer (4) is arranged between the support (5) and the photosensitive elastomer (3), and the photosensitive elastomer (3) Three anti-adhesive layers (2) are compounded on it, and at least one anti-adhesive layer (2) contains a dye, and the maximum absorption wavelength of the dye is 517nm. As a preferred solution, the dye is a red dye or a mixture of red dyes. The dye should use Neozapon  Red 335 or Red Base 543 or Zapon Red 335 / 395 or Neozapon  Red 395 or Neozapon  One of Red 346 or Valifast Red 3306 or Valifast Red 3320 or their mixture. The weight ratio of the dye to the total solids of the release layer material is 1.5%.

[0034] The preparation method of the flexible photosensitive resin plate of the present invention: on the photosensitive elastomer that has been kneaded, at a temperature of 50 ° C and a pressure of 12 MPa, compound one or more anti-a...

Abstract

This invention discloses a method to prepare flexibility photosensitive resin plate. This invention concludes the supporting body, the protective coating, photosensitive elastic body, and between them there is the bond and antisticking zone. There is at least one level antisticking zone on each photosensitive elastic body, and there is dye in at least one antisticking zone. The dye is best redness or redness mixture, and its max absorption is 450-750nm. Under 20-130DEG C, 0.15-14MPa, multiplicity single level or multi-layer antisticking zone on the photosensitive elastic body, and then remove protecting coating, exposition, plate-making, then we can got flexibility photosensitive resin plate. It has high exposure latitude, and its halftone dot decacidized keenesss.

Description

technical field [0001] The invention relates to a photosensitive resin plate and its preparation, in particular to a flexible photosensitive resin plate and its preparation method. Background technique [0002] At present, flexible photosensitive resin plates are widely used in the printing of cartons, flexible packaging, labels and other easily deformed or soft substrates. This technology has matured abroad, and there is no plate manufacturer with better quality in China. The development of flexographic plates that restricts domestic flexographic printing has always been the urgent hope of printing manufacturers. With the rapid increase of my country's export trade and stricter environmental protection requirements, flexographic printing will develop rapidly in China, and the demand for flexographic printing plates will also increase. [0003] Usually, a film with a pattern or text is placed on an unexposed flexographic plate containing photoelastomer, exposed to ultravio...
