ANTIFOGGING STYRENE RESIN SHEET

摘要

PURPOSE:To prepare the title sheet which has stable permanent antifogging properties even after fabrication without detriment to the initial antifogging properties by subjecting the surface of a styrene resin sheet to corona discharge treatment to elevate the surface tension to a specified value and coating the surface with a specified amt. of a fatty acid ester of sucrose. CONSTITUTION:The surface of a styrene resin sheet is subjected to corona discharge treatment to elevate the surface tension to 36-50dyn/cm and coated with a fatty acid ester of sucrose in an amt. of 10-100mg/m<2>.
