Abstract: A composition forms an overcoat layer for an organic photoreceptor by combining an organic silane compound, an acrylic polymer, polyvinyl butyral and a solvent. The organic photoreceptor has increased electrical and mechanical properties, leading to improved life characteristics. Also, unlike when a single material of either acrylic polymer or silsesquioxane is used in forming an overcoat layer, when the composition of the present invention is used, it is not necessary to coat a primer or an adhesive layer, thereby simplifying a coating process and reducing the cost required in forming additive layers.

Abstract: An information storage medium on which interactive contents version information is recorded, a recording and reproducing method, and a recording and/or reproducing apparatus include minimum markup version information and minimum multimedia version information. Since a markup document can be displayed in a reproducing apparatus having a viewer version lower than a specification version of an authoring tool used to author the markup document. If the specification version of the authoring tool is higher than a viewer version supported by the reproducing apparatus, interactive contents may not be correctly reproduced due to specification version information automatically written in the markup document using the authoring tool. Since the information storage medium includes the minimum interactive contents version information and/or the minimum multimedia version information that can be reproduced by the reproducing apparatus, the reproducing apparatus can reproduce the interactive contents smoothly.
