Problems solved by technology

At the same time, the addition of surfactants also reduces the contact angle of the paper surface and enhances the hydrophilicity. The penetration of the glue on the paper surface will be higher than that of other papers. If the knot strength is too high, it becomes very difficult; and the bond strength between the pages inside each copy is not enough, so they cannot be well bonded to each other, but become easy to separate

Abstract

The invention relates to a digital carbonless copy paper, particularly a digital carbonless copy paper which can be matched with separation gel. Curtain coating is carried out on the carbonless copy paper which is 40-170g / m<2>, and the paint comprises pigment, starch, rheologic water retention agent, latex, water-repellent agent, water-resistant agent, lubricant, dispersant and interfacial agent. The optimized paint is coated on the digital carbonless copy paper pages, and the separation gel is matched, so that the printing product with pages can automatically become separate into several parts, and the pages in each part are firmly bound, thereby completely satisfying the demands of the client.

Description

technical field [0001] The invention relates to carbonless copy paper produced in the papermaking industry, in particular to digital carbonless copy paper that can be used in conjunction with separating glue. Background technique [0002] Before the present invention was proposed, the use of digital carbonless copy paper did not require plate making like ordinary printing, which reduced the society's demand for rubber plates and further reduced the demand for oil. So as to obtain various applications. Especially in various fields such as anti-counterfeiting invoices, bank forms, courier orders, and telecommunication business orders, it is necessary to use a multi-part bill. In addition to the different content and the number of pages of each copy, people require that these bills can be automatically separated, that is to say, they do not require strong bonding strength between copies, so they are easier to separate; And between the pages in the middle of each part (or ever...
