摘要： The present invention relates to a resin composition including a polyalkylene carbonate and a self-adhesive film prepared therefrom. The self-adhesive film according to the present invention can not only exhibit excellent adhesion strength to various adherend materials, but also does not leave residues on the surface of the adherend when it is repeatedly used, and particularly can exhibit more stable adhesive characteristics in various environments because its variation rate of adhesion strength depending on the variation of temperature and humidity conditions is low. Furthermore, the adhesion strength of the self-adhesive film can be controlled in a wider range and thus the film can be usefully used for protecting the surface of the adherend of various materials such as a glass, metal, or plastic material.

摘要： The present invention relates to an aqueous acrylic pressure-sensitive adhesive composition, a method of preparing the same and a pressure-sensitive adhesive sheet including the same. More particularly, the aqueous acrylic pressure-sensitive adhesive composition includes 100 parts by weight of a copolymer including 20 to 99 % by weight of an alkyl (meth)acrylate monomer, greater than 0 and 3 % or less by weight of an acrylate monomer including a hydroxy group and greater than 0 and 3 % or less by weight of an unsaturated carboxylic acid; and 0.01 to 5 parts by weight of an anionic surfactant, wherein the copolymer has an average particle diameter of 500 nm or less and satisfies Equation 1 below. The aqueous acrylic pressure-sensitive adhesive composition is prepared by adjusting ball tack and loop tack to predetermined values using a new relational formula, thus exhibiting greatly improved pressure-sensitive adhesion and holding power. 0.55 ≤ X/Y 1.07 wherein X denotes a loop tack value, and Y denotes ball tack strength.
