Problems solved by technology

[0005] By having a cured coating film layer formed of a specific active energy ray-curable primer composition, the initial adhesion and weather resistance are high, but only the silsesquioxane compound and photopolymerization initiator as essential components of Patent Document 1 agent, the adhesiveness to the resin substrate is not at a sufficient level, and in Patent Document 2, since no silsesquioxane compound is contained, the adhesiveness to the inorganic material layer is not at a sufficient level.

Embodiment

[0206] Next, the present invention will be specifically described by way of examples and comparative examples. In the examples, "parts" and "%" are by weight unless otherwise specified.

[0207] In the examples, the value measured under the following conditions by the GPC (gel permeation chromatography) method is used as the number average molecular weight.

[0208] (a) Apparatus: Gel Permeation Chromatography GCP-244 (manufactured by Waters Corporation)

[0209] (b) Column: 2 pieces of Shodex HFIP 80M (manufactured by Showa Denko Co., Ltd.)

[0210] (c) Solvent: dimethylformamide

[0211] (d) Flow rate: 0.5ml / min

[0212] (e) Temperature: 23°C

[0213] (f) Sample concentration: 0.1% Solubility: Completely dissolved Filtration: Mysyoridisk (マイショリディスク) W-13-5

[0214] (g) Injection volume: 0.300ml

[0215] (h) Detector: R-401 differential refraction detector (WATERS)

[0216] (i) Molecular weight calibration: polystyrene (standard)

[0217] In addition, in the examples,...

Synthetic example 1

[0226] Synthesis of polysiloxane segment precursor (a1-1)

[0227] 415 parts of MTMS and 756 parts of MPTS were put into a reaction vessel equipped with a stirrer, a thermometer, a dropping funnel, a cooling pipe, and a nitrogen inlet, and the temperature was raised to 60° C. while stirring while blowing nitrogen. Next, a mixture consisting of 0.1 parts of Phoslex A-4 and 121 parts of deionized water was added dropwise over 5 minutes. After the dropwise addition, the temperature in the reaction vessel was raised to 80° C., and stirred for 4 hours to carry out a hydrolysis condensation reaction to obtain a reaction product.

[0228] 1,000 parts of polysiloxane segments with a number average molecular weight of 1,000 are obtained by removing methanol and water contained in the resulting reaction product under a reduced pressure of 1 to 30 kilopascals (kPa) and at a temperature of 40 to 60°C Precursor (a1-1).

Synthetic example 2、3

[0229] Synthesis of polysiloxane segment precursors (a1-2), (a1-3)

[0230] It carried out similarly to the synthesis example 1, and reacted according to the compounding ratio of following Table 4, and obtained polysiloxane segment precursor (a1-2) and (a1-3).

Abstract

Provided is a laminate obtained by laminating a resin layer (I) and a second layer (II), characterized in that the resin layer (I) comprises a resin composition containing an inorganic particle composite (M) in which inorganic microparticles (m) are bonded, via a siloxane bond at a polysiloxane segment (a1), to a composite resin (A) comprising the polysiloxane segment (a1) having structural units represented by general formula (1) and / or general formula (2) and having silanol groups and / or hydrolyzable silyl groups, bonded via the bond represented by general formula (4) to a vinyl polymer segment (a2).

Description

technical field [0001] This invention relates to the laminated body which laminated|stacked the resin layer (I) and the 2nd layer (II). Background technique [0002] In severe conditions such as outdoors, the role of the protective film to protect the product is important. Especially for automobiles exposed to direct sunlight, abrasion caused by car washing machines, etc., it is required to prevent damage caused by windshield wipers, and to withstand long-term outdoor exposure, the same abrasion resistance, water resistance, and glass. Weather resistance, so forming a highly functional protective film is essential. [0003] In particular, transparent plastic materials, which have attracted attention as glass substitutes in recent years, are expected to be used not only in automobiles but also in building exteriors and solar cell parts due to their light weight and excellent recyclability. Huang became a subject, and looked forward to a protective film that can properly pro...
