Abstract
Abstract A support for an alkali-removable label in the form of a paper label having excellent water resistance and good bottle washing suitability to remove the label and also a label made from such a support. The support consists of a base paper having on a surface thereof an anchor layer produced by applying a radiation-curable composition comprising a radiation-curable resin and a radiation-curable carboxylic acid or a mixture of a monofunctional radiation-curable carboxylic acid and a polyfunctional radiation-curable carboxylic acid and curing the resultant coating by radiation. An intermediate layer comprising a water-soluble polymer or a water-dispersed polymer may be interposed between the base paper and the anchor layer.
