  • Patent number: 12060467
    Abstract: A molded product according to the present invention is a molded product having a structure in which colored particles are dispersed in thermoplastic resin, wherein the colored particles have an average particle size of about 250-3,200 ?m as measured by a particle size analyzer, and are included in an amount of about 0.05-5 parts by weight with respect to about 100 parts by weight of the thermoplastic resin, a three-dimensional pattern is formed on at least one surface of the molded product, and the three-dimensional pattern has a 10-point average roughness (Rz) of about 50-500 ?m and a number of different brightness values of about 30-60. The molded product has excellent impact resistance, excellent heat resistance, and the like, and has an appearance similar to actual fabric.

  • Publication number: 20200262117
    Abstract: An injection molded article of the present invention comprises: a first color resin part with one end having a first thickness, and the other end having a wedge shaped core layer of which the thickness becomes thinner; and a second color resin part with one end having a second thickness, and the other end having a surface layer surrounding the core layer, wherein the upper surface and the lower surface of the surface layer surrounding the core layer has a gradation due to the core layer thereinside. According to the injection molded article having color gradation, it is possible to adjust the size and location of a color gradation section, and it is easy to adjust the thickness.
