A modified lignin having a ratio ((2H+G)/S) of a total of twice of a relative existence ratio H (%) of an H-type skeleton and a relative existence ratio G (%) of a G-type skeleton with respect to a relative existence ratio S (%) of an S-type skeleton, obtained from integrated values measured by .sup.31P-NMR, of 2.5 or more, and an existence ratio of an aliphatic hydroxy group obtained by the same method of less than 20%, a method for producing a modified polyphenol, and a modified lignin-containing resin composition material.

The present invention provides an antiviral substrate that is excellent in antiviral properties, is excellent in transparency or the like, and is capable of maintaining characteristics such as the transparency of a base material and the color of the surface of the base material. The present invention relates to an antiviral substrate in which a cured material of an electromagnetic curable resin containing a copper compound is scattered in the form of islands on a surface of a base material, and at least a part of the copper compound is exposed on a surface of the cured material of the electromagnetic curable resin.

An adhesive sheet utilizes an acrylic resin composition without using a separate primer layer, thus providing excellent adhesion, high reliability due to its excellent light resistance under the sunlight exposure, and excellent elastic modulus, and can be easily used as an adhesive material in various fields such as building materials and automobiles.
