又は酸性剤を同居させて置くと、それらが共に水
可溶の為、大気中に放置しておくだけで発色する
傾向がある。 Bases and acid indicators generally have the property of developing color when exposed to aqueous alkaline or acidic solutions, and have traditionally been used as paper that develops color when exposed to an acidic or alkaline aqueous solution, toys such as hidden pictures, practice tools such as answer sheets, etc. ing. On the other hand, if you want to develop color just by adding water, use an indicator and alkali,
Or, if acidic agents are placed together, they tend to develop color just by leaving them in the air because they are both water soluble.
本発明は、水又は水分だけで発色可能であり、
また大気中に放置して自然発色する現象のない水
中発色シートである。 The present invention can develop color using only water or moisture,
It is also an underwater coloring sheet that does not naturally develop color when left in the atmosphere.

特徴とする水中発色シートである。 The present invention involves kneading an alcohol-soluble base indicator and an aqueous powdered alkaline agent, or an alcohol-soluble acid indicator and a water-soluble powdered organic acid, and an oil-soluble binder in the presence of an oily solvent mixed with alcohol, and then forming the mixture into paper, nonwoven fabric, or film. This is an underwater coloring sheet characterized by coating.

きる。 In the present invention, an alcohol-soluble base indicator and a water-soluble alkali agent that reacts with it to develop a color, or an alcohol-soluble acid indicator and a water-soluble organic acid that reacts with it to develop a color, are mixed in an oil-soluble resin binder with alcohol. Mixed with an oily solvent, it is kneaded in a ball mill to form a paste,
Coloring varnish is produced by encasing it in a varnish-like substance, and the indicator is dissolved in an alcoholic solvent mixed with an oily solvent and mixed into the binder, while the alkaline agent or organic acid remains in powder form. ,
It is dispersed and mixed on the surface of the binder and in the binder. A coloring sheet can be obtained by coating paper, nonwoven fabric, or a filter with the coloring varnish thus obtained using a coater or printing method.

結合して発色する。 When the sheet of the present invention is immersed in water, the color-forming main agent as an alcohol-soluble base or acid indicator contained in the binder and the color-forming auxiliary agent of an alkaline agent or an organic acid dissolve in water, and the surface of the binder dissolves. By absorbing more water, the main coloring agent combines with the OH - or H + ions dissociated from the auxiliary agent to develop color.
