A film laminate for printing comprises a polyolefin film in which at least one side is surface-modified and an anchor layer formed on the surface-modified side of the polyolefin film and containing an oxazoline group-modified resin. The film laminate is prepared by subjecting at least one side of a longitudinally oriented polyolefin film to a corona discharge treatment, forming an ethylene-acrylic acid type copolymer layer on the corona discharge-treated side of the film, laterally orienting the film, and then forming an anchor layer comprising a binder resin, and an oxazoline group-modified resin, on the modified surface of the surface-modified polyolefin film subjected to the corona discharge treatment. The film laminate for printing is excellent in its transparency and it is also excellent in the adhesion to a coated layer.
