(57) Abstract: A surface hydrophilic molded article having a hydrophilic layer formed on a support layer or a hydrophobic coating film formed on the surface of a support, comprising: The hydrophilic layer covers its surface in air A surface hydrophilic molded article made of a material whose water contact angle after heating at 0 ° C. for 5 minutes increases by 8 degrees or more compared to the water contact angle before heating. The surface hydrophilic molded article of the present invention has a sufficient hydrophilic surface as a non-image portion of a printing plate, and an image portion on which an image is written at high speed and with low energy shows sufficient ink receptivity. Since the non-image portion does not cause ink stains, it is useful as a printing plate. This printing plate is Since a complicated process can be omitted, and it can be directly manufactured from information edited by a computer, it is a simple and inexpensive printing original plate. It is useful for molded articles, anti-fog properties, temperature sensors, dew sensors, and over-humidity warning indicators. |
