<P>PROBLEM TO BE SOLVED: To provide a foam which distributes the highly foamed portions of a heterogeneously foamed layer and ultraviolet rays-shielding layers are distributed in an identical pattern, and which has the high overlapping accuracy of the pattern and accurately matches the pattern shapes, and to provide a method for producing the same. <P>SOLUTION: The foam is characterized by having: a heterogeneous foam layer in which highly foamed portions having many formed pores and low foamed portions having a smaller pore-forming density and/or a smaller pore diameter than that of the highly foamed portions are distributed in a prescribed pattern; and ultraviolet rays-shielding layers used for shielding ultraviolet rays and formed on at least one side of the highly foamed portions of the heterogeneous layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
