METHOD FOR SURFACE TREATMENT, SURFACE-TREATED ARTICLE AND DEVICE FOR SURFACE TREATMENT

摘要

A method for surface treatment, characterized in that a surface of a recorded matter comprising a recording medium and an image recorded thereon is treated with a specific treating agent, wherein the treating agent is, for example, a treating agent comprising one or more effective components selected from the group consisting of a sulfur-containing compound, a nitrogen -containing compound, a fluorine-containing compound, a natural resin and a synthetic resin, and water and/or an organic solvent; a surface-treated article treated by using the method; and a surface treatment device for practicing the method. The method can be used for improving the resistance to wheathering, such as the resistance to light and the resistance to gas, of a recorded matter comprising a recording medium and an image recorded thereon with ease and simplicity.
