Embodiment

[0373] Hereinafter, the present invention will be described more specifically with reference to examples. The present invention is not limited to the following examples, and can be appropriately modified and implemented within the scope of adapting to the above-mentioned and later-described gist, and all of them are included in the technical scope of the present invention.

[0374] Preparation of Mixed Composition (q) - No.1q

[0375] 0.5% by mass of Durazane (registered trademark) 1500 rapid cure (manufactured by MERCK) (polysilazane (F)), 0.3% by mass of tetraethoxysilane (metal compound (G)), and the compounds shown in the above Table 5-2 Among (h-I-26), 0.05% by mass of a compound (hereinafter referred to as compound (1)) having an average h10 of 24 (compound (H) containing a siloxane chain) was dissolved in 99.15% by mass of isooctane (solvent ( I)) to obtain the mixed composition (q)-No.1q.

[0376] In addition, Durazane 1500 rapid cure has the structural unit represen...

Abstract

The present invention is a coating comprising at least an outermost surface layer (M) and a layer (K1) in contact with the layer (M), the density of the layer (M) being 0.7 g / cm3 or higher but lower than 1.0 g / cm3, and the density of the layer (K1) being 1.0 g / cm3 or higher but lower than 2.2 g / cm3. Preferably, the layer (M) has a polydimethylsiloxane backbone and / or a trialkylsilyl group.

Description

technical field [0001] The present invention relates to a film and its manufacturing method, and more specifically, to a film having a plurality of layers with different densities and its manufacturing method. Background technique [0002] In various display devices, optical elements, semiconductor elements, construction materials, automobile parts, nanoimprint technology, etc., if liquid droplets (especially water droplets) adhere to the surface of the substrate, the substrate may be contaminated or corroded, And problems such as performance degradation due to the contamination and corrosion. Therefore, in these fields, good water repellency and oil repellency of the substrate surface are required. [0003] A composition in which an organosilicon compound is mixed is known as a composition for forming a film for improving the water-repellency and oil-repellency of the surface of a substrate. [0004] Patent Document 1 discloses a coating composition comprising an organosi...
