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. |

1. A servicing 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 servicing device in response to the transmission of the specific preliminary communication; a demand reception module for receiving, as a response to the specific preliminary communication, a service demand sent from the predetermined external device via the network; and a service provision module for providing the service, wherein at least one of the preliminary communication module, the demand reception module, and the service provision module is a software module, wherein the servicing device further comprises a processor that executes the software module, wherein, prior to receiving the service demand, the external device receives servicing device information request from at least one client device, wherein the external device transmits a response to the client device, the response comprising servicing device information of the servicing device, wherein the servicing device information is obtained by the specific preliminary communication with the preliminary communication module, wherein the client device specifies the servicing device based on the servicing device information provided in the response and transmits a service request to the external device, wherein the external device mediates the received service request from the client device, as a response to the specific preliminary communication, to the demand reception module of the specified servicing device, wherein the service provision module provides the service in response to the received service request, and wherein the servicing device is a printer that provides a printing service. |
