Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] The method 1 of improving the development rate of high-speed printing paper uses nitrogen-containing heterocyclic ketone derivatives as development accelerators, and adds them to the photosensitive liquid of high-speed printing paper. The nitrogen-containing heterocyclic ketone derivatives are mainly five-membered rings. Ketone derivatives, the photosensitive liquid includes photosensitizers, coupling agents and other auxiliary agents, the photosensitizers are FB, FE diazonium salt photosensitizers, the couplin...

Abstract

The invention provides a method for improving the developing rate of high-speed blueprint paper. According to the method for improving the developing rate of the high-speed blueprint paper, a nitrogen-containing heterocyclic one derivative as a display promoting agent is added into a light sensitive liquid of the high-speed blueprint paper, and the nitrogen-containing heterocyclic one derivative is mainly a five member ring one derivative. The light sensitive liquid of the blueprint paper provided by the invention is a novel display developing agent which has a relatively high display promoting effect for the blueprint paper but without influencing the quality guarantee period of the blueprint paper.

Description

technical field [0001] The invention belongs to the technical field of printing paper, and in particular relates to a method for improving the developing rate of high-speed printing paper. Background technique [0002] Printed drawings are internationally accepted copying materials. During manufacture, in order to improve its technical performance, various additives are generally added. Among them, the development enhancer is an essential ingredient. [0003] In the past, there were many types of developing agents used for medium-speed (photosensitive speed) printing paper (hereinafter referred to as "medium-speed paper"), such as phenylphosphoric acid, phenylphosphinic acid and phenylsulfinic acid, as well as thiourea derivatives. substances, polyols, crown ethers, and AD agents in China. However, there are very few development accelerators for high-speed printing of drawings (referred to as "high-speed paper"). [0004] The development accelerator widely used in high-s...
