Problems solved by technology

[0010] Therefore, in the technology of Patent Document 1, in terms of the adhesion of fingerprints, the fluidity of the liquid constituting the fingerprints is greatly different due to the presence of particles, so the amount of adhesion and the simulated adhesion form are insufficient. In the evaluation of the chromatic aberration of the part / uncoated part, the influence of light scattering cannot be evaluated due to the existence of particles, and the chromatic aberration is only evaluated from regular reflection for single incident light, so the state that is actually visible to humans cannot be reproduced
As a result, it is considered that the effect of making fingerprints less noticeable in the technique of Patent Document 1 is not sufficient.

Embodiment

[0175] Next, the present invention will be described based on examples, but the present invention is not necessarily limited to these examples.

[0176] [Fluorine compound A]

[0177] [Fluorine compound A1]

[0178] As the fluorine compound A1, a fluorine-containing dendrimer was used. Its synthesis method is as follows.

[0179] In a 200 mL reaction flask, 32 g of toluene was added, nitrogen gas was injected for 5 minutes while stirring, and the inner temperature was heated until reflux (temperature above 110° C.). In another 100mL reaction flask, add ethylene glycol dimethacrylate (EGDMA) 4.0g (20mmol), 2-(perfluorohexyl) ethyl methacrylate (C6FM) 8.6g (20mmol), 2 , 2.3 g (10 mmol) of dimethyl 2-azobisisobutyrate (MAIB) and 32 g of toluene were injected with nitrogen gas for 5 minutes while stirring to perform nitrogen replacement, and cooled to 0° C. in an ice bath.

[0180]In the refluxing toluene in the above-mentioned 200 mL reaction flask, the content was added drop...

Abstract

An object of the present invention is to provide a molding material in which fingerprints are hard to see while maintaining gloss or transparency, a coating composition capable of forming a layer exhibiting the above-mentioned effects, and a method for producing the above-mentioned layer. A molding material having a layer on at least one side, the layer containing a compound containing fluorine, the specular gloss at 60 degrees specified in JIS Z8741 (1997 edition) is 60% or more, the layer having the following surface properties : The number of peaks exceeding the root mean square roughness (Rq) observed by an atomic force microscope (AFM) is not less than 2500 and not more than 1500 per 25 μm.

Description

technical field [0001] The present invention relates to a molding material excellent in fingerprint resistance, a coating composition capable of forming a layer excellent in fingerprint resistance, and a method for producing the molding material. Background technique [0002] Fingerprints attached to the surface of the object when the human finger touches it (the so-called fingerprint refers to the pattern formed by the lines (ridges) raised from the openings of the sweat glands of the skin at the fingertips, and the traces of the above-mentioned patterns attached to the surface of the object) In this case, there is a problem of giving an unpleasant impression of dirty appearance due to recognition of fingerprints. For example, fingerprints are attached by holding the case of the mobile phone, and the fingerprints are conspicuous and damage the cleanliness. Especially recently, there has been an increase in the number of electronic devices operated with fingers, for example...
