Abstract

A pressure-sensitive adhesive composition attached to a metal surface. The composition includes an acrylic copolymer obtained by polymerizing a monomer mixture, the monomer mixture including: at least one monomer (monomer m1) selected from alkyl(meth)acrylates represented by the formula (I): CH₂═C(R¹)COOR² in which R¹ is a hydrogen atom or a methyl group, and R² is an alkyl group having 1 to 20 carbon atoms, in an amount of 50 to 99.9% by weight based on a total amount of the monomer mixture, and at least one monomer (monomer m2) selected from N-hydroxyalkyl(meth)acrylamides represented by the formula (II): CH₂═C(R³)CONHR⁴ in which R³ is a hydrogen atom or a methyl group, and R⁴ is a hydroxyalkyl group having 2 to 4 carbon atoms, in an amount of 0.1 to 25% by weight based on the total amount of the monomer mixture. The monomer mixture includes substantially no carboxyl group-containing monomer.

Claims

1. A service device for receiving a service demand via a network and providing a service, comprising:

a preliminary communication module for transmitting a specific preliminary communication to a predetermined external device, and causing the predetermined external device to establish communication with the service device in response to the transmission of the specific preliminary communication;

a demand reception module for receiving a service demand sent from the predetermined external device via the network; and

a service provision module for providing the service,

wherein the demand reception module receives a service demand from the predetermined external device as a response to the specific preliminary communication.

2. The service device in accordance with claim 1, wherein the preliminary communication is made at least one of in an always-on state, in an intermittent-on state, and at every specific operation of the service device to the network.

3. The service device in accordance with claim 1, wherein the preliminary communication is made at least either of at a power-on time of the service device and at a time of recovery of cutoff connection of the service device to the network.

4. A service providing method of causing a computer connecting with a network to receive a service demand via the network and provide a service, the service providing method comprising the steps of:

transmitting a specific preliminary communication to a predetermined external device, and causing the predetermined external device to establish communication with the service device in response to the transmission of the specific preliminary communication;

receiving a service demand sent from the predetermined external device via the network; and

providing the service,

wherein the demand reception module receives a service demand from the predetermined external device as a response to the specific preliminary communication.
