Latest Patents

Yijin Ren holds a patent for a positive-working, infrared-sensitive lithographic printing plate and method of imaging. This invention describes a positive-working, infrared imageable coating that includes a phenolic resin containing an o-diazonaphthoquinone derivative. This derivative couples with the resin to partially insolubilize the coating, while an infrared absorbing dye or pigment further enhances the coating's imageability by infrared radiation. The coating is designed to contain only the necessary quantity of infrared radiation absorber and o-diazonaphthoquinone derivative, optimizing both performance and cost. By substituting a portion of the expensive dye with a less costly derivative, the overall cost of the coating is significantly reduced.
