  • Patent number: 9939677
    Abstract: Provided is a back light unit comprising a plurality of LED light source formed on a printed circuit board and a resin layer which is laminated on the LED light source and forwardly induces diffusion of the emitted light wherein the resin layer is made of synthetic resin comprising an oligomer. According to the present invention, an essential light guide plate for a general back light unit configuration is removed and a resin layer mainly consisting of an oligomer is used to guide the light source, and thereby decreasing the number of the light source, minimizing luminance variation when the unit is lighted at a high temperature and kept it for a predetermined time period, and implementing excellent heat-resistant property and optical property.

  • Patent number: 9523017
    Abstract: The present invention provides a mono coating film type waterborne coating composition comprising halogen free polyolefin resin, acryl polyol, acryl emulsion, and a solvent. According to the present invention, adhesion to a polyolefin substrate is excellent, and physical/chemical properties may be maintained with a single coating film instead of the currently used dual coating films, by a halogen free waterborne composition with physical/chemical properties similar to or more excellent than the existing oil coating or halogen-containing coating composition. Since these effects may be sufficiently obtained with a single coating film, consumption of coating may be reduced about 30˜40% compared to the existing method, and particularly, cost reduction may be expected through decrease in equipment required for dual coating film, energy for drying coating film, attractive force of coating, productivity increase, and the like.

  • Publication number: 20130331483
    Abstract: The present invention relates to an organic-inorganic hybrid paint composition comprising (a) an organic resin comprising an acrylic resin, a melamine resin and an epoxy resin; (b) a ceramic resin; and (c) a solvent. The paint composition of the present invention may be easily cured without a curing accelerator unlike conventional paint compositions, and it may form a paint film having generally improved properties of surface hardness and scratch resistance, as well as gloss, adhesion, boil resistance, chemical resistance, and the like.
