A carbonless copy paper

Abstract

The invention belongs to the technical field of carbon-copying paper, and is specifically a carbonless copying paper; it includes a paper body and a U-shaped tear-off paper clip; the top inner wall of the U-shaped tear-off paper clip is connected with a pressure plate through a spring, and the U-shaped tear-off paper clip is opened. There is a notch; the paper body is installed longitudinally in the U-shaped tear-off clip, and is pressed on the inner wall of the bottom of the U-shaped tear-off clip through the pressure plate, and the bottom side of the paper body is provided with a tearing rope at a position perpendicular to the notch; the notch The No. 1 shrapnel is arranged symmetrically near the tearing rope, so that when the tearing rope is pulled up, it can pass through the No. 1 shrapnel and then slide in the slot; through the cooperation of the tearing rope, the U-shaped tearing paper clip and the paper body, the paper body is neatly arranged The torn side wall of the paper body is straight, so that the torn paper body is rectangular, which greatly utilizes the effective range of the paper body, and improves the use range and effect of the paper body , saving a lot of manpower and material resources.

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
