Carbonless copy paper

Abstract

The invention belongs to the technical field of copy paper, and particularly relates to carbonless copy paper. The carbonless copy paper comprises a paper body and a U-shaped paper tearing clamp; a pressing plate is connected to the inner side wall of the top end of the U-shaped paper tearing clamp through a spring, and a notch is formed in the U-shaped paper tearing clamp; the paper body is longitudinally arranged in the U-shaped paper tearing clamp and pressed on the inner side wall of the bottom end of the U-shaped paper tearing clamp through the pressing plate, and a tearing rope is arranged at the position, perpendicular to the notch, of the bottom side of the paper body; and first elastic pieces one are symmetrically arranged at the positions, close to the tearing rope, of the notch,so that the tearing rope can slide in the notch after passing through the first elastic pieces one when being pulled up. Through the match among the tearing rope, the U-shaped paper tearing clamp andthe paper body, the paper body is orderly torn, so that the torn side wall of the paper body is in a linear shape, the torn paper body is in a rectangle shape, the effective range of the paper body is greatly utilized, the using range and the using effect of the paper body are improved, and a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of copying paper, in particular to a carbonless copying paper. Background technique [0002] Carbon paper is a kind of paper whose front is coated with an acid developer and the back is coated with microcapsules containing colorless latent dye. When the paper is overlapped, the microcapsules are broken due to mechanical pressure, and the colorless latent dye overflows and develops color when it encounters acid. , forming an image. This paper can be used in multiple stacks, and it is mostly used as a bill; while carbonless copy paper is a copy paper that does not need to be colored and waxed. When multiple pages of carbonless copy paper are stacked together, multiple copies of the document can be copied directly by printing or writing. Not only is it convenient and clean, but it can also be made into perforated blank computer printing paper to achieve efficient continuous printing and copying; the reason wh...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, solve the problem that due to the high brittleness of carbonless copying paper, the carbonless copying paper is easily damaged during the process of being torn, and the carbonless copying paper is easily torn into irregular shapes, which affects people's use problem; the present invention proposes a carbonless copy paper
