Problems solved by technology

When particles are mixed in, the thickness of the film needs to be thinned in order to form unevenness on the surface, the strength of the coating film is reduced to the point where the film is easily damaged and the properties of the coating film deteriorate
In addition, photochemical properties are sometimes lost

preparation example Construction

[0062] The preparation of the antiblocking curable resin composition of the present invention involves mixing the first and second components, if necessary, together with a solvent, a polymerization initiator, a catalyst, a photosensitizer and / or a curing agent. The weight ratio of the first component: the second component in the antiblocking curable resin composition is preferably 0.1:99.9 to 50:50, more preferably 0.3:99.7 to 20:80, still more preferably 0.5:99.5 to 10:90 . When a polymerization initiator, catalyst and / or photosensitizer is used, based on 100 parts by weight of the first and second components and other optional resins (here, the first and second components and other optional resins are referred to as "resin component"), these agents may be added in an amount of 0.01 to 20 parts by weight, preferably 1 to 10 parts by weight. When a curing agent is used, 0.1 to 50 parts by weight, preferably 1 to 30 parts by weight of the agent may be added based on 100 parts...

[0097] Preparation of acryloyl copolymer

[0098] A mixture of 1263.6 grams of isobornyl methacrylate, 18.9 grams of methyl methacrylate and 67.5 grams of methacrylic acid was stirred. The mixture was added dropwise at a uniform speed within 3 hours to 2430 g of propylene glycol monomethyl ether heated at 110 ° C under a nitrogen atmosphere in a 5000 ml reactor. The reactor was equipped with a stirring blade, a nitrogen gas introduction tube, and a condenser and dropping funnel, and then the mixture was reacted at 110°C for 30 minutes.

[0099] A solution of 540 grams of propylene glycol monomethyl ether containing 67.5 grams of tert-butylperoxy-2-ethyl hexanoate (tert-butylperoxy-2-ethyl hexanoate) was added dropwise within 30 minutes to obtain a number-average molecular weight of 2700 and a weight-average molecular weight 5200 acryl copolymer. The resin had an SP value of 10.2 and a Tg of 113°C.

Abstract

In order to provide a technic for preventing problems such as conglutination (i.e., an adhering phenomena) between layers of a thermoplast film, the invention provides an anti-conglutination hardenable resin composition and application thereof, the composition includes a first component containing at least one or more resin, and a second component selected from at least one or more monomers or low-molecular polymers, wherein the resin of the first component are deposited by phase separation after applying the composition to form superfine non-flatness on surfaces.

Description

technical field [0001] The present invention relates to an antiblocking photocurable resin composition, an antiblocking member comprising a base material and the resin composition applied and cured on the base material, and their production methods. Background technique [0002] When the hard coat layer is applied to a thermoplastic film such as a PET film, the coated film member is sometimes stored by being wound into a roll during production. When another layer is laminated to a resin substrate layer (such as a PET film) on which a hard coat layer has been formed, adhesion and chemical forces between layers cause adhesion. When using the laminated materials, it is sometimes necessary to apply force to separate the laminated materials from each other, and sometimes it is difficult to peel the laminated materials due to too much adhesion or the laminated materials are broken when forcibly separated. [0003] In this case, a coating composition in wh...
