[0022] Examples 1 to 5: A matte release agent for release materials. The matte release agent 1 is located between the release film 2 and the release agent layer 3. The matte release agent has the following quality Percentage component composition:
[0023] Silica particles 2~6%,
[0024] 20-30% acrylic polyol with an average molecular weight of 500-2000,
[0025] Resin of polyoxyalkylene series polyol with an average molecular weight of 200-2500, 35-45%,
[0026] Polyethylene glycol 15~20%,
[0027] 1-hydroxycyclohexyl phenyl ketone-photoinitiator 184 5~10%;
[0028] The particle size of the silica particles is a particle size distribution measured by a laser diffraction and scattering method. The particle size has a peak in the range of 0.1-2um and 1.5-5um, and the average particle diameter is 4um or less.
[0029] The aforementioned release agent layer 2 is silicone oil.
[0030] The aforementioned release film 2 is a polyethylene terephthalate film, a polypropylene film, a polyethylene...
