The present disclosure relates to a thermoplastic resin composition and a molded article including the same. More particularly, the present disclosure relates to a thermoplastic resin composition including 100 parts by weight of a styrene-based resin and 1 to 10 parts by weight of a surface modifier and having a skewness (Rsk) of 0.65 to 1.35 and a molded article including the thermoplastic resin composition. In addition, the present disclosure provides a thermoplastic resin composition that is capable of imparting a rough feeling to the surface of a product and has excellent weather resistance while maintaining mechanical properties and processability equal or superior to those of conventional ASA resins; and a molded article including the thermoplastic resin composition. In particular, due to these properties of the thermoplastic resin composition, a product manufactured using the thermoplastic resin composition may have a luxurious appearance without an artificial plastic feel.

Disclosed is a method of preparing a graft copolymer and a method of preparing a thermoplastic resin composition including the prepared graft copolymer. Also disclosed is a method of preparing a graft copolymer including a process of adding an aromatic vinyl monomer and a vinyl cyanide monomer to a conjugated diene rubber latex that is enlarged with a polymer particle diameter control agent that has a specific glass transition temperature and an average particle diameter in a specific ratio to an average particle diameter of a conjugated diene rubber latex, and graft-polymerizing the same; and a method of preparing a thermoplastic resin composition including the prepared graft copolymer.

Also disclosed is a graft copolymer prepared using the conjugated diene rubber latex enlarged with the polymer particle diameter control agent exhibiting the synergistic effect of improving both impact strength and fluidity.

Disclosed is a method of preparing a vinyl cyanide compound-conjugated diene rubber-aromatic vinyl compound graft copolymer, a method of preparing a thermoplastic resin composition including the same, and a thermoplastic resin composition including the same. More specifically, when a conjugated diene compound and a molecular weight regulator are fed in a split manner during polymerization of conjugated diene rubber, and the content of an emulsifier is reduced, gel content may be reduced. In addition, when enlarged conjugated diene-based rubber latex is prepared by enlarging conjugated diene-based rubber latex using an acid enlarging agent, the enlarged conjugated diene-based rubber latex may have an expanded full width at half maximum in particle size distribution, thereby improving gloss, reflection haze, fluidity, and impact resistance. In addition, deposits may be reduced during injection molding.

An anti-forgery color conversion film includes a photonic crystal structure whose color is converted by an external stimulus such as a breath. The photonic crystal structure includes a first refractive index layer including a first polymer exhibiting a first refractive index; and a second refractive index layer which is alternately laminated with the first refractive index layer and includes a second polymer exhibiting a second refractive index. A consumer who purchases an article including the color conversion film may easily distinguish the authenticity of the article.
