Abstract: The present technology relates to a coating composition for paper making and to a method for manufacturing an eco-friendly type food wrapping paper with improved damp-proofing properties and blocking properties by using same. The water-dispersible coating composition for paper making of the present technology is a coating composition for paper making, which comprises an acrylic polymer resin and a pigment, the acrylic polymer resin containing an acrylate, the pigment containing at least one of clay, talc, and calcium carbonate, wherein the pigment has a particle diameter of 1800 nm or smaller, and is blended with the acrylate while the acrylate is used as a binder.

Abstract: A mobile terminal according to the present invention comprises: a conductive member which forms one side surface of a metal frame of the mobile terminal and which is exposed on the exterior of the terminal; and a plurality of conductive patterns electrically coupled to the conductive member in the metal frame. The plurality of conductive patterns comprises a first conductive pattern and a second conductive pattern which are disposed at both sides with respect to the ground of the conductive member. Here, the first conductive pattern can operate as a radiator of a first antenna and a second antenna, and the second conductive pattern can operate as a radiator of a third antenna and a fourth antenna. The first antenna to the fourth antenna operate as a multi-input multi-output (MIMO) in the same frequency band by a plurality of signals, such that an antenna device having excellent isolation characteristics between a plurality of antenna elements can be provided.

Abstract: Provided are a paper coating material having environment-friendly, water-proof, and oil-proof properties, and a method of manufacturing the same. The paper coating material includes a copolymer emulsion in which a silicon-based polymer and an acryl-based polymer are copolymerized, the copolymer emulsion having the weight average molecular weight of 100,000 to 200,000, and a colloidal aqueous solution of gelatinized polyvinyl alcohol to be mixed with the copolymer emulsion. The environment-friendly paper coated with the environment-friendly coating material according to the present invention is excellent in water-proof, oil-proof and heat sealing properties, harmless to the human body when used for packaging food, and recyclable as a raw material for making paper. It is also biodegradable and therefore, environment-friendly.
