  • Patent number: 9340058
    Abstract: The present invention relates to a blanket for offset printing and a manufacturing method thereof. The blanket for offset printing according to an exemplary embodiment of the present invention comprises a cushion layer, a support layer, and at least two surface printing layers, wherein the at least two surface printing layers comprise a silicon-based resin in which at least one of a hardness value, a fluorine group content value, and a silicon oil content value is different. The blanket for offset printing according to the exemplary embodiment of the present invention comprises the surface printing layer formed in at least two layers to prevent the surface printing layer from being swollen due to ink, thereby reducing a process waiting time and improving a process margin.
    Type: Grant

  • Patent number: 9005743
    Abstract: The present invention relates to a polarizing plate, a method for producing the same, and an image display device comprising the same, and more specifically to a polarizing plate which is characterized by comprising: a) a polarizer, b) a hardening resin layer which is provided on at least one side of the polarizer and formed from a photocurable composition comprising: 4 to 95 parts by weight of (A) a photocurable acrylic polymer, 4 to 95 parts by weight of (B) a poly-functional acrylic monomer, and 1 to 20 parts by weight of (C) a photo-polymerization initiator, based on 100 parts by weight of the photocurable composition, a method for manufacturing the same, and an image display device using the same. According to the present invention, a polarizing plate, which exhibits excellent polarizing properties and durability, has high surface hardness, and may be formed as a thin plate, may be provided.
