In particular, the present invention relates to pressure-sensitive copying paper that provides a high-density color image immediately after printing.

もその一形態として知られている。``Prior Art'' Pressure-sensitive copying paper uses a color-forming agent capsule composition, which is mainly composed of microcapsules containing an oil-based substance in which an electron-donating organic coloring agent (hereinafter simply referred to as coloring agent) is dissolved, as a support. The upper paper is coated on one side, and a coloring agent composition containing an electron-accepting coloring agent (hereinafter simply referred to as coloring agent) as a main component that changes color when it comes into contact with the coloring agent is applied to one side of the support. There are various types of sheets, such as an inner sheet coated with a color former capsule composition on the opposite side, and a lower sheet coated with a color former composition on one side of the support. They are put into practical use as a copy set by combining them in the order of paper - bottom paper. Also known is a self-coloring type pressure-sensitive copying paper which allows pressure-sensitive recording on a single sheet by coating a coloring agent and a coloring agent on the same side of a support.

導体の多価金属塩等の有機呈色剤が知られている。Coloring agents for such pressure-sensitive copying paper include inorganic coloring agents such as acid clay, activated clay, acpulgite, zeolite, bentonite, silica, aluminum silicate, and fesol aldehyde polymers and phenol-acetylene. Organic coloring agents such as phenol polymers such as polymers, polyvalent metal salts of aromatic carboxylic acids or derivatives thereof are known.
このうち有機呈色剤は無機呈色剤に比べ、発色能が高く
、しかも得られた発色像が水分の付着や通常のファイル
保存等で濃度低下を来さないという長所を備えている。Among these, organic coloring agents have a higher coloring ability than inorganic coloring agents, and have the advantage that the color image obtained does not lose its density due to moisture adhesion or normal file storage.
しかし、印字直後の発色濃度が低く、飽和濃度に達する
までに時間を要する欠点(所謂初期発色性に劣る欠点)
があり、その改良が望まれている。However, the disadvantage is that the color density immediately after printing is low and it takes time to reach saturation density (so-called disadvantage of poor initial color development).
There is a need for improvement.
従来、かかる欠点を解消する方法として、発色剤を溶解
する油性物質の粘度を下げて発色剤と呈色剤との接触を
早める方法が行われている。しかし、特に低温条件下に
おいては油性物質の粘度が上がるため、このような方法
では満足すべき結果が得られていないのが現状である。Conventionally, as a method to overcome this drawback, a method has been used to reduce the viscosity of an oily substance that dissolves the color former to accelerate the contact between the color former and the color former. However, because the viscosity of the oily substance increases especially under low temperature conditions, it is currently not possible to obtain satisfactory results with this method.

However, in most of the pressure-sensitive copying papers obtained by using these phosphate esters in combination, a phenomenon is observed in which the color images are significantly deteriorated by light. However, when tributyl phosphate is used in combination, the initial color development is improved without deterioration of the color image due to light, but since tributyl phosphate is liquid at room temperature, the surface of the color former layer is It is sticky and may cause trouble during printing.

This improves coloring performance. Although the reason for this effect is not necessarily clear,
It is presumed that the above compound improves adsorption and compatibility between the oil-based substance containing the color former and the organic color former, resulting in pressure-sensitive copying paper with extremely excellent initial color development ability. .
