Problems solved by technology

However, although these conventional surface treatment agents can impart corresponding antistatic properties or anti-fogging properties to synthetic polymer films, there is a problem of significantly destroying the sliding properties of the synthetic polymer films. Problems with the original physical properties of the synthetic polymer film, such as transparency

[0108] Surface treating agents (P-2) to (P-11) and (R-1) to (R-6) were prepared in the same manner as the surface treating agent (P-1). These were made into the aqueous liquid of the surface treatment agents (P-2)-(P-11) of Examples 2-11 and the surface treatment agents (R-1)-(R-6) of Comparative Examples 1-6, respectively. Including the surface treatment agent (P-1) of Example 1, these contents are collectively shown in Table 2.

[0123] The aqueous solution of the surface treatment agent (P-1) prepared in Test Part 2 was further diluted with water to prepare a 1% aqueous solution of the surface treatment agent (P-1), and stretched at a film thickness of 100 μm with a rod coater. After coating the aqueous solution on the polypropylene film, it was dried with hot air at 70° C. for 3 minutes to obtain a surface-treated polypropylene film.

Abstract

Provided are a surface treatment agent useful for producing synthetic polymer film having antistatic and anti-fog properties without damage of inherent physical properties and excellent smoothness, and a process for surface treatment agent using the same. The surface treatment agent comprises vinyl copolymer and lubricant in weight ratio of copolymer / lubricant ranged from 30 / 70 to 90 / 10. The vinyl copolymer is prepared by comprising 10 to 60 wt.% vinyl monomer represented by formula; 40 to 90 wt.% vinyl copolymer having molecular weight of 10000 to 100000 and formed of the vinyl monomer of formula and other vinyl monomer copolymerizable therewith (wherein R1 is hydrogen or methyl group, R2 is alkylene group having 1-4 carbon atoms, R3 and R4 are alkyl groups having 1-6 carbon atoms). The lubricant is at least one or two selected from organic carboxylic acid, organic carboxylate, organic carboxylic ester, organic amide carboxylate, polyethylene wax, silicone oil, silica particles, silicone resin particles and talc powder.

Description

[0001] [Technical field to which the invention belongs] [0002] The present invention relates to a surface treatment agent for synthetic polymer film (hereinafter referred to as surface treatment agent), a surface treatment method for synthetic polymer film (hereinafter referred to as surface treatment method) and surface treatment synthetic polymer film. Synthetic polymer film, in order to impart antistatic (antistatic) and anti-fogging properties to the synthetic polymer film, a surface treatment agent is coated on its surface. Of course, such a surface treatment agent is required not to damage the synthetic polymer film. The original physical properties, such as transparency, can impart antistatic properties and anti-fogging properties to the synthetic polymer film. In recent years, the process of molding and printing of the synthetic polymer film has been speeded up, and at the same time, it is required to be able to A surface treatment agent that imparts excellent sliding ...
