Abstract
To provide a white resin composition which is excellent in concealment property, toughness and printing adhesion, and a shrinkable white substrate, and a shrink label which enable protection of a content and imparting of designability without coloration of a container.SOLUTION: A white resin composition is used for forming a shrinkable white substrate in a shrink label which has an overcoat layer, a printing layer and a shrinkable white substrate in this order, and has a direct printing layer in the shrinkable white substrate, and contains titanium dioxide (A) and a thermoplastic resin, wherein the titanium oxide (A) has an average primary particle diameter of 0.13-0.28 μm and purity of 95-99.9%, and the thermoplastic resin has a crystallization temperature higher than a glass transition temperature by 60°C or more and the glass transition temperature of 65-110°C.SELECTED DRAWING: None
