For this type of postcard,
Although several kinds have already been put on the market, none of them are still sufficient in terms of performance or cost. For example, the one described in Japanese Utility Model Publication No. 63-6870 is
It is designed so that peeling occurs from a non-adhesive resin layer other than the adhesive layer that is the bonding surface, and once the label is peeled from the postcard, it cannot be easily re-bonded, and the label peeling is extremely stable. Although it has features, since the adhesive label used has a multi-layered structure, many steps are required for its manufacture, resulting in extremely high manufacturing cost and a small cost merit due to the low shipping fee. There is.

That is, when an electrophotographic system is used as a printer when outputting personal information to a postcard, transfer of toner to a label is likely to occur at the time of peeling, and a recorded image may not be readable. Therefore, the present inventors have previously made various proposals for improving this phenomenon, but none have been perfect yet, and further improvement is desired.

製造方法である。The present invention relates to a removable pressure-sensitive adhesive postcard obtained by bonding a pressure-sensitive adhesive sheet for labels having an adhesive layer on a support to a non-adhesive postcard sheet under high pressure. The adhesive layer of the pressure-sensitive adhesive sheet for labels is provided by coating a support with a coating liquid containing an adhesive and a release agent having an average particle diameter in the range of 1 to 1000 μm as basic components. A method for producing a pressure-sensitive adhesive sheet for a label, comprising:

By using the above, it was found that the transfer of the toner can be improved to a practical level, while the use of the one having an average particle size of more than 1 mm makes it impossible to obtain a stable quality after smearing for a long time. It has been found that the use of a release agent having an average particle size in the range of 1 μm to 1 mm is most preferable. It has also been found that, among others, the use of particles having an average particle size in the range of 3 to 50 μm reaches a very good level in terms of prevention of toner transfer and long-term smear stability.
