調の手触りを有する塗膜が得られた。EXAMPLES The present invention utilizes polytetrafluoroethylene which is conventionally contained directly in a coating resin composition in order to improve the friction property of a coating film. This has been achieved as a result of synthesizing polytetrafluoroethylene composite resin particles by paying attention to friction characteristics and lubrication characteristics and studying the composite resin particles as an extender pigment of a coating material. The main component of the polytetrafluoroethylene composite resin particles of the present invention is composed of polytetrafluoroethylene powder or particles and a resin carrying them. Polytetrafluoroethylene is in the form of powder that is generally used as a lubricant, a release agent, an abrasion improver, an antiblocking agent, and the like. The supported resin may be various resins such as an acrylic resin, an epoxy resin, a polyester resin, a urethane resin, and a polyolefin resin, but is not particularly limited, and may be a binder resin used in the coating composition. Select according to the affinity. However, in order to obtain a feel of a finger closer to that of genuine leather, it is preferable that the resin is a soft resin having rubber elasticity in mechanical properties, and since the coating composition generally contains an organic solvent component, it is solvent resistant. It is desirable that it has excellent properties. The above is the main component of the polytetrafluoroethylene composite resin particles, but it is also possible to use a coloring pigment together for coloring the polytetrafluoroethylene composite resin particles, and various stability for the purpose of improving thermal stability, light stability, etc. You may add an agent. The polytetrafluoroethylene composite resin particles of the present invention are prepared by previously synthesizing the composite resin particles, and then mechanically embedding the polytetrafluoroethylene powder, or a method of fusion bonding, polytetrafluoroethylene powder and resin monomer. It can be obtained by polymerizing a mixture with a cation or an oligomer by a suspension polymerization method or the like. Polytetrafluoroethylene composite resin particles thus obtained as an extender pigment of the coating composition,
Alternatively, when it is colored, it can be used as a coloring pigment to obtain a leather-like coating composition having a novel leather-like touch. In this case, when the polytetrafluoroethylene composite resin particles are spherical, the average particle diameter is 1
The range is preferably within 00 μm. Further, in the case of a shape other than spherical, those having an average major axis of 100 μm or less are suitable. The reason for this is that when polytetrafluoroethylene composite resin particles having an average particle diameter or an average major axis of 100 μm or more are applied to a coating composition, a problem such as a rough surface finish of coating may occur, which is not preferable. Examples of the binder resin of the coating composition containing the polytetrafluoroethylene composite resin particles described above include resins used in their respective fields. For example, in the coating composition, acrylic resin, urethane resin, epoxy resin, alkyd resin, polyamide resin, organosiloxane resin, polyester resin and the like can be exemplified. These resins are selected according to the environment in which the coating composition is used and the coating substrate, and are not particularly limited. Further, it may be used together with an extender pigment, a coloring pigment, resin particles, an abrasion resistance improver, an ultraviolet absorber and the like which are generally used. Among the coating compositions of the present invention, the mechanical properties of the cured film have a breaking strength of 20-.
When a binder resin having a rubber elasticity of 500 kg / cm 2 and a maximum elongation of 20% or more is used, a coating composition having a good leather-like touch can be obtained. Use of a binder resin having a breaking strength of the cured film of 20 kg / cm 2 or less is not preferable because the coating film tends to become brittle. Also, when a binder resin having a breaking strength of the cured film of 500 kg / cm 2 or more is used, the coating film tends to be hard, so that it is difficult to obtain a good tactile sensation. Regarding the mechanical properties of the resin carrying polytetrafluoroethylene, a soft resin having rubber elasticity can be selected to obtain a coating composition having a better tactile sensation. Furthermore, the polytetrafluoroethylene composite resin particles have very good fluidity between each other as compared with ordinary polytetrafluoroethylene powder particles, and thus serve as a lubricant with excellent lubricating performance. Moreover, if an inexpensive resin is used as the resin carrying the polytetrafluoroethylene powder particles, an inexpensive lubricant having excellent lubricating performance can be obtained. [Example 1] Lubron L-2 was added to a mixture of 35 parts by weight of Praxel 220AL (polycaprolactone diol manufactured by Daicel Chemical Industries Ltd.) and 10 parts by weight of Praxel 303 (caprolactone triol manufactured by Daicel Chemical Industries Ltd.).

100 g of this isocyanate-containing paste was gradually added and stirring was continued for 30 minutes. Then, the temperature was raised to 80 ° C. for 1 hour while continuing the stirring, and the stirring was continued for further 24 hours. As a result, 80 g of black urethane resin particles encapsulating polytetrafluoroethylene particles having a particle diameter of 5 to 200 μm were obtained. . The black urethane resin particles encapsulating the polytetrafluoroethylene were washed with water, dried and then classified to 100 μm or less. [Example 2] 50 parts by weight of Praxel 220AL (polycaprolactone diol manufactured by Daicel Chemical Industries, Ltd.) and 10 parts by weight of Praxel 303 (caprolactone triol manufactured by Daicel Chemical Industries, Ltd.) were added to 1 part by weight of carbon black to 39 parts by weight. 100 parts by weight of a paste was obtained by dispersing with a part of methyl ethyl ketone by a paint shaker. To 100 parts by weight of this paste, 20 parts by weight of Desmodur W (diisocyanate manufactured by Sumitomo Bayer Urethane Co., Ltd.) and 10 parts by weight of Coronate EH (isocyanate oligomer manufactured by Nippon Polyurethane Co., Ltd.) were added and sufficiently stirred. A 1 liter separable flask equipped with a thermometer and a stirrer was charged with 500 ml of a 1% carboxymethylcellulose aqueous solution, and 100 g of this isocyanate-containing paste was gradually added while stirring at high speed, and stirring was continued for 30 minutes. While continuing stirring, 15 g of Lubron L-2 (polytetrafluoroethylene powder manufactured by Daikin Industries, Ltd.) was gradually added to the dispersion medium.
After that, the temperature was raised to 80 ° C. for 1 hour and the stirring was continued for further 24 hours, whereby 80 g of black urethane resin particles coated with polytetrafluoroethylene particles having a particle diameter of 5 to 200 μm were obtained. The black urethane resin particles were washed with water, dried, and then classified to 100 μm or less. [Example 3] Number average molecular weight 3000, hydroxyl value 112 m
To 40 parts by weight of gKOH / g polyester resin, 30 parts by weight of toluene, 25 parts by weight of ethyl acetate, and 5 parts by weight of carbon black were added and dispersed by a paint shaker to obtain a paste. 20 parts by weight of black urethane resin particles containing the polytetrafluoroethylene particles obtained in Example 1 in 50 parts by weight of this paste, 1 part by weight of Mizukasil P-801 (fine powder hydrous silicic acid manufactured by Mizusawa Chemical Industry Co., Ltd.), 0 of dibutyltin dilaurate 0.01 part by weight was added to obtain a coating composition. 100 parts by weight of this coating composition was added to Sumijour N-75.

After drying for a minute, a coating film having a very moist leather-like touch was obtained. Moreover, it was confirmed that the coating film had the same level of frictional property as the conventional coating film containing polytetrafluoroethylene particles directly, but the scratch resistance was considerably improved. Example 4 A paste prepared by dispersing 100 parts by weight of Neoletz R-960 (urethane emulsion manufactured by ICI) and 50 parts by weight of the black urethane resin particles obtained in the above Example 2 in 100 parts by weight of water with a paint shaker.
