Getting issues with using Like with escape to find '%:%'

I am getting error when I use the following query

select * from table_1 where sql_text like '%!:%' escape '!';

ORA-01424: missing or illegal character following the escape character

There is no issue with the following:

select * from table_1 where sql_text like '%!_%' escape '!';

Can someone explain what is the issues here? I want to find all rows which has : or :" in the sql_text column.

Any suggestion will be highly appreciated.
