PURPOSE: A tackifier composition, an acrylic adhesive, and a manufacture method thereof are provided to fundamentally prevent aging of adhesive and to improve adhesive force for polar surface and non-polar surfaces. CONSTITUTION: A tackifier composition comprises a second acrylic monomer having a first acrylic monomer, hydroxy group, or carboxy group, a photo initiator which has absorption region of 100-400 nano meters wavelength and a molecular weight controller. A manufacturing method of the tackifier composition includes a step of bulk polymerizing by irradiating ultraviolet ray of 100 - 400 nano meters on a resin composition. An acrylic adhesive composition comprises acrylic polymer as a base material resin and the tackifier composition as tackifier. |
