Problems solved by technology

[0004] However, even if these materials are used, it is difficult to exhibit sufficient density to a wide range of materials ranging from low-polarity polyolefin resins to acrylic resins, polyester resins, polycarbonate resins, ABS resins, and other polar resins. In particular, it is difficult to exhibit the above-mentioned adhesion in low-temperature construction at around 100°C

[0196] Into a 2-liter autoclave fully replaced with nitrogen, 900 ml of hexane and 90 g of 1-butene were charged, 1 mmol of triisobutylaluminum was added, the temperature was raised to 70° C., and then propylene was supplied so that the total pressure was 7kg / cm 2 G, add 0.30 mmol of methyl aluminoxane, and add racemic-dimethylsilylene-bis{1-(2-methyl-4-phenyl) in an amount of 0.001 mmol converted to Zr atoms Indenyl)} zirconium dichloride, continuously supplying propylene while keeping the total pressure at 7kg / cm 2 G side was polymerized for 30 minutes. After the polymerization, degassing was performed, and the polymer was recovered in a large amount of methanol, and dried under reduced pressure at 110° C. for 12 hours. The obtained propylene / 1-butene copolymer (low crystalline olefin resin A-1) had a melting point of 78.3° C., a melting enthalpy of 29.2 J / g, a Mw of 330,000, and a propylene cont...

[0198] 3 kg of the above-mentioned propylene / 1-butene copolymer (low crystalline olefin resin A-1) was added to 10 L of toluene, and the temperature was raised to 145° C. under a nitrogen atmosphere, and the copolymer was dissolved in toluene. Furthermore, 382 g of maleic anhydride and 175 g of di-tert-butyl peroxide were supplied to the system over 4 hours with stirring, followed by stirring at 145° C. for 2 hours. After cooling, a large amount of acetone was added to precipitate the modified copolymer, which was filtered, washed with acetone, and vacuum-dried.

Abstract

The purpose of the present invention is to provide: a coating agent which provides a coating film that exhibits excellent adhesion to a polyolefin resin base that is not subjected to a preliminary surface treatment, while exhibiting good adhesion to a base having high polarity at the same time; a decorative film which has at least one layer that is formed of the coating agent; and a molded body which is decorated with the decorative film. A coating agent of the present invention is characterized by containing (A) an olefin polymer that has a melting enthalpy within the range of 0-50 J / g and a weight average molecular weight (Mw) as determined by a GPC method of from 1 × 104 to 1,000 × 104 and (B) a synthetic hydrocarbon oil that has a kinematic viscosity at 40°C of 30-500,000 cSt.

Description

technical field [0001] The present invention relates to a coating agent, a decorative film, and a molded body. More specifically, it relates to a coating agent, a decorative film, and a molded body useful as paints, primers, and adhesives. Background technique [0002] Polyolefin-based resins such as polypropylene and polyethylene are inexpensive and have many excellent properties such as moldability, chemical resistance, water resistance, electrical properties, and safety, and are therefore widely used. However, polyolefin-based resins are hydrophobic materials with low polarity, and thus it is difficult to closely bond polar resins such as acrylic resins, polyester-based resins, polycarbonate-based resins, and ABS resins. Therefore, the present situation is that it is difficult to laminate the above-mentioned polar resin on the surface of the polyolefin-based resin, and it is difficult to perform decoration with ink, paint, or the like. [0003] As resins having adhesion ...
