Document Type and Number:
Japanese Patent JP6976348
Kind Code:
B2
Abstract:
Components of a system for marking, identification and segregation of plastic waste, including waste of multi-layer and multi-component plastics is disclosed herein. The coating material for marking plastics contains a base of the coating material and fluorescent markers dissolved or dispersed in the base of the coating material. The composition of the coating material or the way it is printed constitutes an arbitrary code, consistent with the adopted marking system. The coating material can be washed off from the surface of marked material with a washing agent. The code contained in the composition of the coating material or in the way it is printed is readable after irradiating with appropriate wavelength. The use of printed graphic or text patterns with at least two coating materials containing different fluorescent markers allows for creation of a practically unlimited number of individual identification codes.
