(63) <Evaluation>

(64) With respect to each composition for a release agent, curable properties, force required peeling (hereinafter, referred to as peel strength), residual adhesion ratio, and surface resistivity were evaluated and measured by the following method. The results are shown in Tables 1 and 2.

(65) [Curing Properties]

(66) The obtained composition for a release agent was applied to a PET film having a thickness of 38 m using barcoater, and heated at 120 C. for 1 minute in a hot air drier to form a release agent layer. The release agent layer was rubbed with a finger ten times, and the presence or absence of cloudiness or defects was visually observed, and evaluated in accordance with following criteria.

(67) : cloud and rub-off were not observed.

(68) x: cloud and rub-off were observed.

(69) [Peel Strength]

(70) A release agent layer was formed in the same manner as in the curing properties, and polyester adhesion tape (product name: nitto-31B, manufactured by Nitto Denko Corporation) was laminated on the surface of the release agent layer, and a load of 1976 Pa was applied to the adhesion tape so as to adhere the polyester adhesion tape to the release agent layer. Using a tensile testing machine, the polyester adhesion tape was peeled from the release agent layer such that the angle between the polyester adhesion tape and the release agent layer became 180 (peeling speed: 0.3 m/min), and then, peel strength was measured. As the peel strength is smaller, the adhesion sheet can be easily peeled after the adhesion sheet is adhered to the release agent layer. That is, the adhesive sheet becomes a film having easy-peeling properties.

(71) [Residual Adhesion Ratio (Subsequent Adhesion Ratio)]

(72) A polyester adhesion tape was laminated on the release agent layer in the same manner as in the measurement of peel strength. Then, the laminated structure was left at room temperature for 20 hours, or the laminated structure was subjected to heat treatment at 85 C. for 20 hours. Next, the polyester adhesion tape was peeled from the release agent layer. The peeled polyester adhesion tape was adhered to a stainless panel. Thereafter, using a tensile testing machine, the polyester adhesion tape was peeled from the stainless panel and then, peel strength X was measured.

(73) A polyester adhesion tape that had not been adhered to a release agent layer was adhered to a stainless board, and using a tensile testing machine, the polyester adhesion tape was peeled from the stainless board and then, peel strength Y was measured.

(74) In accordance with the formula (peel strength X/peel strength Y)100(%), residual adhesion ratio was calculated.

(75) As the residual adhesion ratio becomes larger, the release properties the release agent layer becomes excellent, and deterioration of adhesion properties of polyester adhesion sheet which had been adhered to the release agent layer can be suppressed.

(76) [Surface Resistivity]

(77) Using Hiresta MCP-HT450 manufactured by Mitsubishi Chemical Corporation and a probe MCP-HTP12, surface resistivity was measured under applied voltage of 10 V. The result OVER in Table means that surface resistivity was too high to measure it.

(80) With respect to the compositions for a release agent according to Examples 1 to 22, peel strength was low, and surface resistivity was low.

(81) With respect to Comparative Examples 1 to 3 which did not contain the conductive component and Comparative Example 5 in which the amount of conductive component was small, surface resistivity was too high and could not be measured the value.

(82) With respect to Comparative example 4 in which the amount of the conductive component was large, and the amount of the release component was relatively small, surface resistivity was high.

(83) With respect to Comparative Example 6 in which the substituent of the amine compound coordinated to or bonded to the surplus sulfonate groups within a polystyrene sulfonate is the primary amine, the liquid was not stable, the conductive complex was incompatible with a silicone resin and therefore, uniform film could not be formed. As a result, surface resistivity could not be measured.

(84) With respect to the compositions for a release agent of Comparative Examples 7 and 8 in which the water content was more than 5%, the curing failure has occurred and the peeling property was reduced.

(85) With respect to the composition for a release agent of Comparative Example 9 which was produced by using the isopropanol dispersion of polystyrene sulfonate having a mass average molecular mass of 1,000,000, dispersion stability was low and conductivity did not express.
